Variations of Exhaust Gas Temperature and Combustion Stability due to Changes in Spark and Exhaust Valve Timings
The effects of spark timing and exhaust valve timing change on exhaust gas temperature during cold start of an SI engine are studied through engine bench tests. It is observed that the exhaust gas temperature increases when the spark timing and valve timing are retarded individually or simultaneously, due to late combustion or slow flame speed. However, using COVimep it is also investigated tha...
متن کاملGas Flow into Rotary Valve Intake and Exhaust Mechanism in Internal Combustion Engine
Simple design of a rotary valve system is capable of controlling intake and exhaust gases, which will eliminate the need of known complex mechanisms. The cost of material and production, maintenance, and noise level of the system can be further reduced. The new mechanism enables the elimination of the overlapping of valves work that reduces gas leakage. This paper examines theoretically the gas...
متن کاملExhaust Gas Recirculation in On·board Diagnostic System
Introduce electronic control exhaust gas recirculation EGR system in the passenger cars and light duty vehicles was made because of fuel direct injectionengines. In this engines temperature combustion process is a higher then other type engine and in this connections NO, emissions were higher to. Simultaneously was appearing problems to electronic exhaust gas recirculation control in connection...
متن کاملAn Approach to the Prototyping of an Optimized Limited Stroke Actuator to Drive a Low Pressure Exhaust Gas Recirculation Valve
The purpose of this article is to describe the design of a limited stroke actuator and the corresponding prototype to drive a Low Pressure (LP) Exhaust Gas Recirculation (EGR) valve for use in Internal Combustion Engines (ICEs). The direct drive actuator topology is an axial flux machine with two air gaps in order to minimize the rotor inertia and a bipolar surface-mounted permanent magnet in o...
