DEVELOPMENT OF A VARIABLE CONTROLLED INERTIA CHARGING SYSTEM FOR NATURALLY ASPIRATED DIESEL ENGINES FOR HEAVY DUTY TRUCKS
A method of controlling the inertia charging effect for the diesel engine has been developed. The new method covers the whole range of engine speeds and load conditions. Details of the study are described. One of the measures that can be taken to offset the deterioration of engine performance caused by the reduction of exhaust gas emission is to improve the combustion characteristics by increasing excess air ratio. Though inertia charging can provide more excess air from the engine, this system has to have some fixed factors, such as tuned pipe length and diameter. So the resonsance zone is also fixed within a narrow engine speed range. And, moreover, outside this range, the air quantity is reduced below that without inertia charging. Therefore, variable control of inertia charging with a mechanism to change the tuned pipe length is considered for this system. The intake air quantity is thus controlled to improve engine performance over a wide speed range at both full and partial load. The engine can get higher brake mean effective pressure of 0.90 MPa at peak quantity to minimize gas exchange loss.
