Surface texture is one of the most important topics in today's world of design, development and performance. As tolerances are shrinking and performance demands are increasing, surface texture is rapidly becoming one of the most important aspects of engine and vehicle performance. Every moving component on a vehicle or engine is influenced by surface texture in one or more of the following ways: vibration, sealing, adhesion, traction, emissions, safety, durability, wear/failure analysis. Many of the industry's top warranty issues (leaks, noise, vibration, etc.) are a direct result of surface texture implications.

Additive manufacturing (AM), with origins in the 1980s, has only more recently emerged as a manufacturing process of choice for functional part production, adding to the suite of choices a designer has available when designing a part for manufacturing. Like other traditional processes like casting and machining, AM has its set of constraints. An added layer of complexity comes from the fact that there are several different AM processes, and some of the design constraints are process-specific.

Transient emission peaks have become an important fraction of the total emissions during the standardized test cycles for passenger car Diesel engines. This paper is concerned with their reduction, in particular of nitric oxides (NOx) and particulate matter (PM) emissions, by online receding horizon optimal control. It is based on former works in which alternative target quantities for engine control were proposed, namely in-cylinder oxygen concentrations before (O2,BC) and after combustion (O2,AC). The actual work is concerned with testing an in-cylinder oxygen concentrations based control in simulation as well as by a real-time implementation on a turbocharged common rail passenger car production Diesel engine. The promising results confirm the choice of these concentrations as sensible control references and the feasibility of a real-time use in a model predictive control implementation.

The exhaust gas is getting to higher temperature in order to adapt higher power and lower fuel consumption of the engines, and the exhaust manifolds tends to use in more severe conditions. The exhaust manifolds of 660cc engines of the turbo specification had been made of the high-Si spheroidal graphite cast iron containing a small amount of Mo so far, but now it cannot help using Ni-resist for higher heat resistance. However, Ni-resist is extremely expensive because it contains much 35wt% nickel of the rare metal. Therefore, the development of the new cast iron having the performance and the cost between the conventional cast iron and Ni-resist is demanded. With such a background, the new spheroidal graphite cast-iron “Vanadium cast iron” for the low-cost exhaust manifolds that greatly improved the heat resistance than the conventional cast iron was developed.

The exhaust pipes of the motorcycle were always exposed to high temperature exhaust gas. There was a problem of the tarnish or the rust during use, and it might be sometimes complained from a user. Therefore we developed new surface treatment and could prevent these problems. New surface treatment is “Nano-film Coating” by the DC reactivity magnetron sputtering method (PVD method). We developed SiOxNy ceramic Nano-film of the thickness of 20-150 nm on the metal substrates. This Nano-film was evaluated heat resistance, corrosion resistance, wear resistance and optical characteristics. It is able to get these performance satisfied enough. And the metal coloration is possible by controlling a refractive index and a film thickness of the Nano-film. The film was deposited in a three-dimensional shape by controlling the reactive gas composition, the gas ratio and sputtering power. The exhaust parts are colored by three patterns that is “transparent and colorless”, “gold” and “blue”.

Abradable Powder Coatings improve the efficiency of blowers, compressors, engines, pumps, etc., by reducing operating clearances and friction. Characteristics of lubricious, abradable clearance control coatings are discussed and related to performance and durability improvements in pumps, engines, and other devices. The coatings can be applied very thick and sometimes provide an interference fit when a device is assembled. During initial operation, the coating breaks in to form a perfect fit between mating parts. Controlled abrasion even accounts for thermal and stress related distortions in components as the coating wears in. Once the optimum fit is achieved, stresses on the coating are reduced and the break-in process stops. The coatings support and maintain hydrodynamic oil film regime. Provided data indicate that durability, low friction, anti-scuff properties of the coating maintain tighter operating clearances and higher efficiency for the life of the device.

The demands of the engine, transmission and power train industries concerning wear and corrosion resistance have increased in recent years. Conventional processes like carburizing and gas nitriding are facing their limits to some extent. Pulsed plasma nitriding is arousing more and more interest in these industries. The lifetime of components can be increased dramatically by the use of this surface treatment process due to the special layer composition it imparts. Pulsed plasma nitriding may also present economic benefits, as in many cases the final, very cost-intensive hard machining can be omitted. Furthermore, pulsed plasma nitriding has considerable environmental advantages compared to other heat treatment processes. It can be easily integrated into mechanical manufacturing, as there is no open flame and nearly no waste gas.

The cold metal transfer process (CMT) was introduced into industry more than 4 years ago. This process was developed to reduce heat transfer to the substrate during the welding of metals. The CMT process has distinct advantages over the conventional gas metal arc welding process (GMAW), in which the heat input is much greater. CMT was developed specifically for the dip transfer method, which until now has been notoriously difficult to work with. An example of a process which has been made easier through the use of CMT is the butt welding of thin sheet aluminium (0.3mm) using 1.2mm filler material. Unlike conventional processes, this can be achieved without the use of backing protection or heat sinks. Another example is the welding of mild steel using CO₂ as a shielding gas. With CMT, this can be done with a significant reduction in spatter.

Exhaust gas recirculation (EGR) cooler fouling has become a significant issue for compliance with nitrogen oxides (NOx) emissions standards. In order to better understand fouling mechanisms, eleven field-aged EGR coolers provided by seven different engine manufacturers were characterized using a suite of techniques. Microstructures were characterized using scanning electron microscopy (SEM) and optical microscopy following mounting the samples in epoxy and polishing. Optical microscopy was able to discern the location of hydrocarbons in the polished cross-sections. Chemical compositions were measured using thermal gravimetric analysis (TGA), differential thermal analysis (DTA), gas chromatography-mass spectrometry (GC-MS), x-ray photoelectron spectroscopy (XPS), energy dispersive spectroscopy (EDS) and x-ray diffraction (XRD). Mass per unit area along the length of the coolers was also measured.

Surface temperature and heat flux were measured in a single cylinder SI engine piston when uncoated and with two different surface coatings: a metal TBC and YSZ. Average heat flux into the piston substrate was 33 % higher with the metal TBC and unchanged with the YSZ relative to the uncoated surface. The increase with the metal TBC was attributed to its surface roughness. However, the metal TBC and YSZ reduced peak heat flux into the substrate surface by 69 % and 77 %, respectively.

Gasoline detergency is related to deposits at various parts of the engine and therefore has impact on vehicle driveability and emission properties. The widely used engine tests such as CEC F-20 M111 and ASTM D6201 Ford 2.3L tests take tens of hours and thus are very expensive and time consuming to carry out. A new simulation test for gasoline detergency on intake valve cleanliness using lean-oxygen gum method was developed and the correlation of test results with M111 engine test was studied. Gasoline samples with different detergency levels were tested with both the lean-oxygen gum method and the M111 engine test. Test results of 24 gasoline samples show satisfactory correlation between the lean-oxygen gum method and the M111 engine test (R₂=0.7258).

In this study, experiments were performed on a 4-stroke, 6-cylinder turbocharged, direct injection (DI) diesel engine using two oxygenated fuels blended with European auto diesel fuel (DF) to investigate the engine performance and exhaust emissions with special interest in fine particles. In the investigation, 20 vol% jatropha biodiesel was added to the DF; while 6.31 vol% diethylene glycol dimethyl ether (DGM) was added to the DF to maintain same oxygen percentage (2.26 wt%) in the blended fuels. The fuel is designated as DDGM for the DF-DGM blend and DB20 for the DF-biodiesel blend. The fine particle number was determined with a scanning mobility particle sizer (SMPS). Carbon monoxide (CO), total unburnt hydrocarbon (THC), smoke, total particulate matter (TPM) and oxides of nitrogen (NOx) were also measured.

A new direction in biocomposite manufacturing is to integrate natural fibers and recycled polymers for manufacturing of some innovative products for various industrial uses including automotive under hood parts. The performance of these new materials are comparable to existing ones even with the replacement of synthetic fiber with biodegradable natural fiber from agricultural residue and with the shift from pure polymer to recycled polymer. Thermoplastic are reinforced with flax fiber mostly used to develop biocomppsite. Most of the research reviewed indicated that very limited work had been done on using flax fiber with recycled post consumer thermoplastic to make biocomposite. The goal of this research is to develop recycled biocomposite material by using flax fiber as a reinforcement and recycled post consumer thermoplastic as matrix and streamline the manufacturing process with optimal processing condition and fiber percentage.

The success of stratified combustion is strongly determined by the injection and ignition system used. A large temporal and spatial variation of the main parameters - mixture composition and charge motion - in the vicinity of the spark location are driving the demands for significantly improved ignition systems. Besides the requirements for conventional homogeneous combustion systems higher ignition energy and breakdown voltage capability is needed. The spark location or spark plug gap itself has to be open and well accessible for the mixture to allow a successful flame kernel formation and growth into the stratified mixture regime, while being insensitive to potential interaction with liquid fuel droplets or even fuel film. For this purpose several different ignition concepts are currently being developed. The present article will give an ignition system overview for stratified combustion within Delphi Powertrain Systems.

In this paper, in support of developing an advanced non-pneumatic lunar tire, a dynamic interaction model between non-pneumatic tire and sand is presented using the Finite Element Method (FEM). This non-pneumatic tire is composed of three major components: a critical shear beam, two inextensible circumferential membranes, and deformable spokes. The non-pneumatic tire made of segmented cylinders is described in detail. The tire is treated as an elastic deformable body with the inertia effect is included. Lebanon sand found in New Hampshire is modeled as because of the availability of a complete set of material properties in the literature. The Drucker-Prager/Cap plasticity constitutive law with hardening is employed to model the sand. Numerical results show contact pressure distribution, distributions of various stresses and strains, deformation of non-pneumatic tire, and deformation of sand.

To improve the energy absorption capacity of front-end structures during a vehicle crash, a novel 12-sided cross-section was developed and tested. Computer-aided engineering (CAE) studies showed superior axial crash performance of the 12-sided component over more conventional cross-sections. When produced from advanced high strength steels (AHSS), the 12-sided cross-section offers opportunities for significant mass-savings for crash energy absorbing components such as front or rear rails and crush tips. In this study, physical crash tests and CAE modeling were conducted on tapered 12-sided samples fabricated from AHSS. The effects of crash trigger holes, different steel grades and bake hardening on crash behavior were examined. Crash sensitivity was also studied by using two different part fabrication methods and two crash test methods. The 12-sided components showed regular folding mode and excellent energy absorption capacity in axial crash tests.

Quasi-static axial cutting of AA6061-T6 and T4 round extrusions were completed using a specially designed cutter with multiple blades. The round specimens had a length of 200 mm, a nominal outer diameter of 50.8 mm, and a wall thickness of 3.175 mm or 1.587 mm. Four different cutters, constructed from heat-treated 4140 steel, having 3, 4, 5 and 6 blades on each cutter with a nominal tip width of 1.0 mm were used to penetrate through the round extrusions. A clean cutting mode was observed for the AA6061-T6 and T4 extrusions with wall thickness of 3.175 mm with an almost constant steady state cutting force. A braided cutting mode was observed for extrusions with both tempers with wall thickness of 1.587 mm, which resulted in a slightly oscillating steady state cutting force. For all extrusions with a wall thickness of 3.175 mm, the steady state cutting force increased with an increase in the number of cutter blades.

The biofidelity of the Hybrid III headform in impact is largely dependent on local head geometry and viscoelastic mechanical properties of its polymer skin. Accordingly, for accurate simulation of the ATD headform in computational models, a quantitative understanding of the mechanical properties of skin material is required at a variety of strain rates and strain amplitudes. The objective of this study was to characterize the head skin material of the Hybrid III test dummy for finite deformations and at moderate strain rates for blunt impact simulation using finite element models Head skin material from a single ATD was tested using uniaxial compression. A viscoelastic constitutive model with separable temporal and elastic responses was used to characterize the nonlinear and viscoelastic material behavior.

This paper deals with an investigation of the road roughness on the vehicle ride comfort using semi-active suspension system. A mathematical model of quarter vehicle for semi active suspension system is developed to evaluate vehicle ride comfort. The rolling resistance and power losses are also investigated. The power consumed in rolling resistance and power dissipation in suspension for passive and semi-active suspensions are evaluated. The obtained results showed that ride comfort increases as the road roughness is decreased. Comparisons between passive and semi-active suspensions systems in terms of ride performance and power dissipation are also discussed.
