The Influence of Engine Speed on Exhaust Emission of Four Stroke Spark Ignition Multi Cylinder Engine
An experimental study is carried out to investigate engine performance parameters and methods of reducing emissions from spark ignition engine. Fuel efficiency is one of the major concerns for the users, the designers and the manufacturers of internal combustion (IC) engines, The effect of increasing the temperature of cylinder liner has the advantage of reducing the specific fuel consumption b...
متن کاملMotion planning for experimental air path control of a variable-valve-timing spark ignition engine
Air path control of a spark ignition engine without an EGR loop, equipped with variable-valve-timing (VVT) actuators, is addressed in this paper. VVT devices are used to produce internal exhaust gas recirculation, providing beneficial effects in terms of fuel consumption and pollutant emissions reduction. However, VVT actuators affect the fresh air charge in the cylinders. This has an impact on...
متن کاملInfluence of Injection Timing on the Performance of Dual Fuel Compression Ignition Engine with Exhaust Gas Recirculation
–Fast depletion of fossil fuels demands an urgent need to carryout research to find viable alternative fuels such as Hydrogen, LPG and CNG. The gaseous hydrocarbons seem to be best immediate option presently available[1]. The remarkable feature of gaseous fuels are the absence of mineral impurities, the consistency in quality and the convenience and efficient in use. LPG is used widely as a co-...
متن کاملThe Effects of Ethanol–gasoline Blend on Performance and Exhaust Emission Characteristics of Spark Ignition Engines
The effects of unleaded gasoline and unleaded gasoline–ethanol blends on engine performance and pollutant emissions were investigated experimentally in a single cylinder, four-stroke spark-ignition engine with variable engine speeds (2600–3500 rpm). Four different blends on a volume basis were applied. These are E0 (0% ethanol + 100% unleaded gasoline), E3 (3% ethanol + 97% unleaded gasoline), ...
متن کاملControl Oriented Model of a Dual Equal Variable Cam Timing Spark Ignition Engine
A control oriented engine model is developed to represent a spark ignited engine equipped with a variable cam timing mechanism over a wide range of operating con ditions Based upon laboratory measurements a continuous nonlinear low frequency phenomenological engine model is developed With respect to a xed cam timing engine the VCT mechanism alters the mass air ow into the cylinders the torque r...
