In this review research, the air capacity of four stroke deck’s
engine is investigated and studied thoroughly from the considerations of
Introduction; effect of residual-gas temperature; effect of operating conditions
on volumetric efficiency which constitutes the following: Effect of engine size,
engines with similar cylinders, effect of the pressure ratio {𝑃𝑒 /𝑃𝑖}, effect of fuel
injection on volumetric efficiency, effect of design on volumetric efficiency
which in turn includes (i.e. effect of design on {ΔT}); effect of valve overlap;
inlet system design; important general relations; multi cylinder inlet systems;
effect of exhaust pipe length; effect of heat transfer; effect of camshaft on
volumetric efficiency which includes the following: Camshaft profile, the effect
of lift camshaft, duration, lobe separation, overlap and profile; effect of
atmospheric conditions on performance from the following considerations:
Effect of changes in atmospheric temperature, and effect of inlet temperature;
effect of coolant temperature; intake and exhaust system heat transfer; the study
of the influence of valve profile from the following points of view: Types of
valves, poppet valves, inlet valve flow capacity and exhaust valve flow
capacity; the study of the effect of valve or port timing on engine performance
from the viewpoints of the impact of valve events upon engine performance and
emission, the parameters or variable quantities; effects of valve overlap; Valve
peak lift; industry trends; Exhaust Gas Recirculation (EGR) systems; variable
valve timing; phase changing systems; profile switching systems; variable event
timing systems; variable lift systems; and electro-magnetic valve actuation
systems.
