In order to meet the EU6c, 6×〖10〗^11 # / km particulate number emission target that will be introduced in 2017, some gasoline direct injection (GDI) engines might require the use of particulate filters (GPF). The lifetime of wall-flow filters is influenced by the composition of the engine lubricant due to the potential of the lubricant to contribute to ash accumulation in the GPF. In order to anticipate the potential need for new, lower ash, lubricants an endurance test was performed using a commercially available GPF. An innovative radio-labelling method was used to identify the amount of lubricant derived ash trapped in the GPF. After the endurance test, during which 9 kg of 1% sulphated ash oil was consumed, approximately 50 g of ash had accumulated in the GPF. This amount is only 56% of the expected amount based on fresh oil sulphated ash concentration and oil consumption.

API-CF grade lubricants cater to majority of light and heavy duty commercial vehicles on road in India. Soot accumulation in lubricating oil can result in engine wear and lubricant's viscosity increase thereby affecting its pumping ability and drain interval. Due to faster lubricant degradation and with emergence of newer engine technologies, there is increasing demand on improving performance of lubricants particularly with respect to soot dispersancy. This paper describes the development of test method for evaluating the lubricant's dispersancy/anti-wear characteristics up to 6% soot level on a commercial BS II, 4-cylinder turbocharged diesel engine. The test severity was generated in order to match real time environment by incorporating various engine hardware modifications like inlet air restriction, retarded injection timing, increased fuel delivery, auxiliary oil sump unit, and change in injector pressures.

The growing transportation sector worldwide has opened up a way forward not only for the scientists & researchers but also for the OEMs to find out the options for fuel efficient automotive vehicles with reduced emissions during their usage. The demand of automotive vehicles has been doubled in last few years and in turn the market for lubricants and transmission fluids are flourishing. Several new formulations of lubricants are getting popularized with major suppliers to achieve the end user expectation in terms of fuel economy benefits, engine life and emissions. The market trend is continuously moving towards the improvement in lubricant formulation to the lower viscosity ranges and in this direction Indian Oil Corporation Limited is into development of multi-grade low viscosity range of engine oils (lubricants) which is said to be providing the benefits in terms of fuel economy.

A variety of performance fluids and lubricants are used in automobiles and in automotive manufacturing processes. These include engine oils, driveline fluids, paints, forming lubricants, and many others. Controlling the rheological properties of these fluids is crucial to achieve desired performance and product qualities. In this study, we have applied Extensional Rheometry to gain a new insight on the performance of automotive fluids. Traditionally, rheological experiments focused on the study under shearing flow. However, the real operations contain both shear and ‘extensional’ (or ‘elongational’) flow components. In this paper, we have investigated the extensional behavior of automotive fluids using a Capillary Breakup Extensional Rheometer. (The extensional viscosity express how “sticky” the fluid is, whereas shear viscosity means how “slimy” the fluid is.)

Exhaust Gas Recirculation system (EGR) has been used for years for NOx emissions control in commercial vehicle applications. Emissions limits are tighter with every regulation while durability requirements are increasing, so EGR systems manufacturers must be able to provide high performance and robust designs even with high thermal loads. Commercial vehicle market is characterized by lower production rates than passenger car programs, but same engine has multiple applications with totally different engine calibrations. In some cases it is necessary to design two or more EGR systems for an engine platform, with the consequent impact on cost and development timeline. The optimal design of and EGR system needs to take into consideration several topics related with performance and durability: efficiency and pressure drop, fouling, boiling, thermal fatigue, vibrations, pressure fatigue and corrosion among others.

The interaction of three bio-lubricant base oil candidates with seventeen combinations of surface treatment were studied, comparing wear scar volumes and coefficient of friction results. Substrates were initially ground or superfinished, a combination of Dymon-iC™ DLC, an ultra-fine shot blasting method doped with Tin and Molybdenum Disulfide, a calcium based chemical dip and nano fullerene, were used. DLC is a well reported to reduce frication and wear, some reports suggest wear in coated contacts is independent of the type of lubricant used, others report that bio-lubricants offer reduced friction and wear in combination with DLC. Shot blasting can also reduce wear and friction, dimples act as lubricant reservoirs, making hydrodynamic lubrication more likely. Work has also explored the performance of surface texturing in combination with coatings, some finding higher friction with surface texturing and DLC.

Deposit formation on the turbocharger compressor housing can lead to compressor efficiency degradation, which leads to loss of fuel economy and increase in CO2 and NOx emissions. To understand the role that engine oil composition and formulation play in these deposits which arise from oil aerosols and particulates from the closed crankcase ventilation, fIve different lubricants were run in a fired engine test to evaluate turbocharger compressor efficiency. Basestock group, additive package, and viscosity modifier treat rate were varied in the lubricants tested. After each test was completed the turbocharger compressor cover and backplate deposits were characterized. A laboratory oil mist coking rig has also been constructed, which generated deposits having the same characteristics as those from the engine tests. By analyzing results from both lab and engine tests, correlations between deposit characteristics and their effect on compressor efficiency were observed.

The combustion of cylinder lubricating oil is one of the major resources of PM emissions of low-speed 2-stroke marine engines. For pre-mixed gas engines, the auto-ignition of cylinder oil might result in knock or more hazard abnormal combustion — pre-ignition. The evaporation is a key process of the auto-ignition of cylinder oil droplets. The evaporation behavior has a profound impact on the auto-ignition and combustion processes of cylinder oil droplets. This paper applied a suspending apparatus to investigate the evaporation characteristics of cylinder oil droplets and base oil droplets. The effects of environment temperature and droplet diameter on the evaporation process were measured and analyzed. The results indicate that the evaporation of cylinder oil includes heating, evaporation, pyrolysis, and polymerization. Under high temperature conditions, the pyrolysis process caused the explosion of the oil droplets, and the evaporation curve appeared intensive waving.

In this paper, the influence of metallic content of lubricating oils on diesel particles were investigated. Three lubricating oils with different levels of metallic content were used in a two cylinder, four stroke, direct injection diesel engine. 4.0 wt. % and 8 wt. % antioxidant and corrosion inhibitor (T202) were added into baseline lubricating oil to improve the performance respectively. Primary particle diameter distributions, fractal dimension of aggregates and particle nanostructure were compared and analyzed by Transmission Electron Microscope. The graphitization degrees of diesel particles from different lubricating oils were analyzed by Raman spectroscopy. Conclusions drawn from the experiments indicate that the metallic content increases the primary particles diameter at 1600 rpm and 2200 rpm. The primary particles diameter ranges from 5 nm to 70 nm and the distribution conformed to Gaussian distribution.

Electric oil pumps (EOP) for automobiles are used to lubricate and cool moving mechanisms and supply oil pressure to components. Conventional EOPs consist of two separate units including a driver and a pump system comprised of a motor and a pump, which, as a result, impedes layout flexibility for vehicles. To overcome this shortcoming, we have developed an ECU-integrated oil pump in which a driver, a motor and a pump are incorporated as a single unit. In the course of the project, we focused on improving vibration resistance and developing a compact design. The first challenge was to improve vibration resistance because of the driver located in close proximity of the powertrain. Since the driver is installed on the motor unit via bus bars that are electrically welded, the joints of the driver and the bus bar become susceptible to vibration.
