The simulation research of the air flow through the throttle valve
is intended to elaborated the flow character.
The air intake throttle valve
and EGR valve are connected through a highly flexible coupling (cam-link mechanism), allowing the new unit to be applied to various engine parameters, including displacement and output, merely by changing the shape of the connection between the two valves (cam profile).
For throttle valve
5 (TV5): [h.sub.32] = [h.sub.33] (32)
In contrast to the company's previous valves using solenoid control, this newest EDR-Di throttle valve
employs a d.c.
Isuzu said the buses' engines may stall as the mechanism may become unable to supply air to the engines with carbon soot accumulating to hinder the movements of their throttle valves
, called butterfly valves.
It is to be equipped with an all-new engine with an 11.3:1 compression ratio, an electronic throttle with a throttle valve
made of resin, a start-stop system and a near-hybrid system that converts brake energy into electric energy in order to recharge the car's battery.
Because the mixture is homogenous, the compression ratio can be increased without fear of detonation, and there is no need for a throttle valve
in the intake air stream.
