The enhancement of efficiency will play a more and more important role in the development of future (small) internal combustion engines. In recent years, the Atkinson (or Extended Expansion) cycle realized over the drive train attracted increasing attention. Several OEMs have been doing investigations on this efficiency-increasing principle in the whole range from small engines up to automotive engines up to now. In prior publications, the authors outlined the remarkable efficiency potentials of an Extended Expansion (EE) cycle. However, for an internal combustion engine, a smooth running performance as well as low vibrations and noise emissions are relevant aspects. This is especially true for an Extended Expansion engine realized over the drive train. Therefore, design measures concerning friction and NVH need to be taken to enable possible series production status. Basically, these measures strongly depend on the reduction of the free mass forces and moments.

Three dimensional reactive CFD plays a crucial role in IC engine development tasks complementing experimental efforts by providing improved understanding of the combustion process. A widely adopted combustion model in the engine community for (partially) premixed combustion is the G-Equation where the flame front is represented by an iso-level of an arbitrary scalar G. A convective-reactive equation for this iso-surface is solved, for which the turbulent flame speed ST must be provided. In this study, the commonly used and well-established Damköhler correlation is compared to a novel, physically sound closure derived from an algebraic closure for the scalar dissipation of reaction progress as proposed by Kolla et al. [1].

In this paper, the development and design of a new four stroke two cylinder diesel engine family of 1.3 liter capacity are discussed. Also, the salient features, performance and emission quality are presented. The transfer of design principles used in large engines resulted in providing highly enhanced wear life of the engine. The bore and stroke are 95 and 91 mm to maintain the piston velocity within 8 m/s. The engine is naturally aspirated (NA) for bmep less than 7.6 bar and turbocharged and intercooled (TCIC) for higher bmep. The high bmep engine uses fillet hardened chromium molybdenum steel. The engine is using a crankcase integrated with the flywheel housing and the timing case at the front; it reduces the cost and the number of parts and also makes the engine highly rigid against torsion and bending to form an integral part of a tractor chassis. For the tractor application, a cast iron sump in place of a light steel sump is designed for improving the rigidity.

In recent years, more attention has been focused on environment pollution and energy source issues, as a result, increasingly stringent fuel consumption and emission legislations were implemented over the world. For automakers, enhancing engine’s efficiency as a must contributes to lower vehicle FC. To reach this goal, Geely auto started develop 3-cylinder 1.0L turbocharged direct injection gasoline engine to achieve a challenging fuel economy target while maintaining fun-to-drive and NVH performance. The high performance (specific torque 205Nm/L and specific power 100kw/L) and excellent part-load BSFC were defined, which lead to a real challenge for combustion system design. Considering air/fuel mixture, wall impingement and even future potential for lean burn, a symmetrical layout of central direct injection with 200bar injection pressure was determined.

Currently the downsizing of IC Engine has become the mainstream to meet fuel economy and emission regulations. It is required that higher power output while with lighter weight that is actually a daunting challenge for a common four-stroke IC engine, because it needs lots of new technologies and high manufacturing cost. For recent years the two-stroke opposed piston engine has drawn much attention in many developed countries for fundamental advantages itself. Double firing frequency means the increased power density causes smaller engine size and lighter weight, however, the low scavenge efficiency has been assumed the main disadvantage for a two-stroke engine for a long period, and adverse to combustion efficiency. The uniflow scavenging process was investigated by the transient CFD simulation for multiple Cases. The influence of port timing and exhaust back pressure on scavenging was analyzed for two different intake port layouts.

In the present paper we consider a new design of adaptive suspension systems of vehicles with better technical characteristics and functional abilities in comparison with existing designs. We have developed the following main suspension components of vehicles: a lockable adaptive shock absorber with a wide range of control performance, implementing "lockout" mode by means of blocking adaptive shock absorber, and an elastic element with progressive non-linear characteristic and automatic optimization of localization of work areas. Our patents confirm the novelty and efficiency of our major design decisions. Advantages of our developments in the vehicle suspensions are the following: 1) it should be noted that when the vehicle is in a wide range of speeds in a so-called "comfort zone", we have managed, by applying the non-linear elastic element, to reduce significantly the stiffness of the elastic suspension elements in compare with the regular structures - at least in two times.

With the advent of most advanced diesel engines the demand for upgraded engine cooling modules capable of handling more heat rejection in a smaller space is surging. Moreover, the variance in the operating conditions, i.e., the simultaneous cooling demands for peak load as well as partial load in different ambient conditions of the vehicle operation, broadens the scope of development of a cooling system. Also, the cooling system needs to be configured judiciously so as to cater effective cooling at peak loads and efficient cooling at partial loads. This research paper deals with a cooling system developed using modularity approach in order to have a control over tuning of subsystems for varying operating conditions and also to achieve the performance targets with a compact design adhering to packaging constraints. Kuli simulation of different designed configurations were carried out for identification of best concept.

The existing head cover is having external oil and blow by separation unit, which is not only costlier but also complex and leads to increase the overall height of engine which was difficult to integrate in new variants of vehicles. Existing head cover sealing system was also not foolproof and with slight variation in part dimensions, there were high chances of leakage. A new head cover has been designed with internal baffle type oil and blow by separation system to ensure efficient separation and proper packaging of the system in new varients.The new system has been finalized after 26 DOEs of different wire mesh sizes and different baffle plate size and positions. The final system has two bowl shaped separation unit with wire mesh with two cup type oil separation passages and one baffle plate for separating blow by. The system works on condensation and gravity method. The blow by is guided through a well-defined passage integrated in aluminum cylinder head cover itself.

Wheel-loaders’ sub-systems like engine, driveline, hydraulics, cooling and mechanism are becoming increasingly more integrated and complex. This is mostly caused increased demand of energy efficiency, electronic controls and performance requirements from competitors and customers. In order to understand the complex sub-system interactions it requires engineers to use a common simulation platform which captures the multi-domain nature of a wheel-loader. Engineers from different sub-system groups can use such model to validate the full system requirements. Wheel-loader sub-system are multi-domain (controls, mechanism, hydraulics, thermal etc.) in nature. This paper describes the process of the development of a Multi-domain simulation of a wheel-loader. Working hydraulics, kinematics of working tool, driveline, engine and cooling system are modelled in LMS Amesim. Contacts between boom/bucket and bucket/ground are defined to constrain the movement of the bucket and boom.

Emission, fuel economy and productivity in non-road mobile machinery (NRMM) depend largely on drive cycles. Understanding drive cycles can provide the in-depth information and knowledge that help the system integrator better optimize the vehicle management system. Some non-road engine test cycles already exist nowadays. However, these cycles are mainly for engine emission regulation purpose, and not closely tied to real world applications. Therefore, from both industries and academia, it has been the common practice to instrument and retrofit a vehicle, assign a professional driver operate the retrofitted vehicle for real testing, and compare the results to the baseline vehicle under the similar operating conditions. Obviously this approach is time consuming and resource intensive. In this paper, we attempt to address this issue by introducing a method of constructing standard drive cycles from in-field operation data.

This paper presents an overview of a project called “Modelling and Simulation Tools for Systems Integration on Aircraft (MISSION)”. This is a collaborative project being developed under the European Union Clean Sky 2 Program, a public-private partnership bringing together aeronautics industrial leaders and public research organizations based in Europe. The provision of integrated modelling, simulation, and optimization tools to effectively support all stages of aircraft design remains a critical challenge in the aerospace industry. In particular the high level of system integration that is characteristic of new aircraft designs is dramatically increasing the complexity of both design and verification. Simultaneously, the multiphysics interactions between structural, electrical, thermal, and hydraulic components have become more significant as the systems become increasingly interconnected.

Abstract This paper proposes an integrated system’s approach towards design of aero-engine subsystems - seals, bearing chamber, generator and power system. In a conventional design approach, the design of the overall system is typically broken-down into subsystems. Therefore, the focus is not on the mutual interaction between different components or subsystems, resulting in a lack of characterization of the overall system performance at the design phase. A systems design approach adopts a much broader outlook, focusing on the overall optimization of the system performance. This paper is divided into two parts. The first part presents an integrated approach for modelling the electrical, mechanical and hydraulic subsystems of aero engines, in order to analyze the fluid dynamics interactions and reduce the transversal shaft vibrations. For this, an in-line starter/generator and an air-riding seal are studied.

Abstract Detailed machine models are, and will continue to be, a critical component of both the design and validation processes for engineering future aircraft, which will undoubtedly continue to push the boundaries for the demand of electric power. This paper presents a survey of experimental testing procedures for typical synchronous machines that are applied to brushless synchronous machines with rotating rectifiers to characterize their operational impedances. The relevance and limitations of these procedures are discussed, which include steady-state drive stand tests, sudden short-circuit transient (SSC) tests, and standstill frequency response (SSFR) tests. Then, results captured in laboratory of the aforementioned tests are presented.
