The research consists of adopting continuous variable length intake manifold on diesel engines where compression and suction waves provide better swirl and pressurization methodology. Steering returnability refers to the automatic returning response of the steering wheel after taking a full turn while vehicle is being steered during driving.
The spray propagation during the injection process was measured with high-speed shadowgraphy. It becomes cardinal to study the mixture preparation in engines to understand the injection strategy that helps in achieving the prime objectives of lower emission and reliable operation. The test results of the eMachine with the inverter are presented to show the drive system operating the 6-phase current controller and inverter.
In this study, three-dimensional computational fluid dynamics CFD is used for prediction of auto-ignition characteristics of diethyl ether DEE and ethanol. However, the phenomena in a combustion chamber are very complicated because of various environmental conditions, and the discharge and combustion phenomena under a strong gas flow remain unclear.
It is generally known that generating a flow field in the cylinder is effective for reducing combustion fluctuation and shortening the combustion period.
The exterior cylinders 1 and 4 are operated in parallel, with the fourth cylinder deactivated in efficiency mode. The power ranges for these applications are typically between 1 kW and 10 kW. Aerodynamics, Passenger car, Drag coefficient, Roof rack, Fuel economy.
The two experimental approaches namely direct photography by high speed camera and measurement of scattering oil quantity at low speed condition have been tried. By focusing on superior technology in the development of automotive emission catalysts, we help our customers to produce more fuel-efficient vehicles and meet present and future requirements of environmental legislation.
The lean gasoline-air mixture was provided and was ignited by small amount of pilot diesel fuel injection constant volume combustion. A high-compression ratio, supercharged single cylinder engine was used in this experiment. Also when radiator is mounted in the rear, the rate of heat transfer for a radiator surface area reduces due to less available source air.
The focus on low cost, compact solutions runs through the work.
The lubricant requirement of motorcycles differs from that of passenger cars. Also, parameters like piston profile, oil film thickness optimized for least friction. Aim of this paper is to analyse the probable causes of such a vehicle drift, to objectively measure actual brake steer and corresponding vehicle drift during braking using a unique methodology.
This has made both Original equipment manufacturers and suppliers to align their strategies towards achieving this goal. Further analysis is carried out with different new design of roof rack.
Technical Paper Connected vehicles technology is experiencing a boom across the globe. Technical Paper In DISI engines spray distribution and atomization directly influence mixture formation, the quality of combustion and the resulting emissions.
Technical Paper The application of more efficient compression ignition combustion concepts requires advancement in terms of fuel injection technologies. So air-fuel mixing is strongly influenced by the injection pressure, geometry of the nozzle duct and the hydraulic characteristics of the injector.
The severity of the engine oil with respect to different viscosity grade and their impact on motorcycle performances and the engine components were studied on two motorcycles.
Technical Paper The purpose of this study was to investigate how autoignition leads to the occurrence of pressure oscillations. Our catalysts perform in a wide range of powertrains, including gasoline and diesel engines, natural gas, and alternative fuels, and are increasingly important in engines supporting mild and full hybrid vehicles.
The requirements, relating to power and duty cycle, flow down from the vehicle to the eMachine: Monday, 5 November — PM Therefore, simulation is becoming an essential part of the engine calibration optimization.
After generating the hot spot area, the mechanical compression of an asymmetric double piston unit is added in four-stroke operation, which brings auto-ignition of gasoline.
Engine geometry and operation parameter such as injection strategy and compression ratio can affect the reactivity of fuels in cylinders as well as the gas temperature increase rate which are the important factors in controlling RCCI combustion.
The challenging part is on achieving the stringent emission norms without compromising the engine fuel economy, performance and NVH factors.
