Reduction of Exhaust Gas Emissions and Fuel Economy Using Variable Valve Timing engine.

Numerical study of the effect of fuel injection timing on the ignition delay, performance parameters and exhaust emission of gas/dual fuel diesel engine using Computational Fluid Dynamics

Today, due to the various usage of compression ignition engines in urban transportation, as well as the need to reduce exhaust emissions and control fuel consumption, the use of alternative fuels has become common in diesel engines. Gaseous fuel is one of the most common alternative fuels that can be used in diesel engines. The utilization of alternative fuels in compression ignition engines re...

Emission Reduction Strategies for Small Single Cylinder Diesel Engine Using Valve Timing and Swirl Ratio

Small diesel engines are widely used for commercial vehicle and passenger car applications due to their higher torque requirements, fuel economy, and better thermal efficiency. These engines are exposed to different operating and environmental conditions and hence emissions from these engines are erratic. Strategies are required to enhance performance and reduce engine-out emissions considering...

Reduction of emissions and fuel consumption of diesel engine by using common rail fuel injection and aftertreatment systems

In this experimental study, the fuel system of the OM364 diesel engine manufactured by IDEM company, which operates in the basic mode with inline fuel pump and mechanical governor control, is upgraded to a common rail system with electronic control by the ECU. Also, emmssion of exhaust gases is reduced by SCR and DOC catalysts then performance and emmission parameters of engine are compared i...

Impact of Methanol–Gasoline Fuel Blends on the Performance and Exhaust Emissions of a SI Engine

Performance and Exhaust Gas Emissions Analysis of Direct Injection Cng-diesel Dual Fuel Engine

Existing diesel engines are under stringent emission regulation particularly of smoke and particulate matter in their exhaust. Compressed Natural Gas and Diesel dual fuel operation is regarded as one of the best ways to control emissions from diesel engines and simultaneously saving petroleum based diesel fuel. Dual fuel engine is a conventional diesel engine which burn either gaseous fuel or d...
