Effects of inlet manifold dimensions on volumetric efficiency of engines;

Because the intake pipe effect of gas fluctuation can improve volumetric efficiency and the performances of en- gine,the paper employs the AVL BOOST software,based on the original TJ376QE gasoline engine,to optimize the design of the variable intake manifold length.

A new method for determination of the charging and the volumetric efficiency of the individual cylinder in a multi-cylinder internal combustion engine was proposed.

But charge efficiency decreases when back pressure of exhaust increases because of the pressure loss in three-way catalytic converter (TWC).

This paper presents the simulation calculation and experimental results of charging efficiency of vehicle rotary engine with compound intake ports,and analyzes the characteristics of the charging efficiency varying with loads and speeds of the engine as well as distribution relationship of mass flow rate between the peripheral and side ports varying with engine speeds.

This paper states the gas exchange process of four-stroke gasoline engines, and analyzes a variety of elements that affect the charging efficiency.

Packaged fresh tilapia fillet with different inflatable volume(V) and fish weight(W) ratio, stored at freezing-point storage,indexes such as micro-organisms,gravy leakage rate,TVB-N values and TBA values indicated the impact that different inflatable ratio on the quality of fresh tilapia fillet.
