PURPOSE: To adjust air-fuel ratio easily at the time of idle operation by detecting a degree of opening of a flow rate control valve by voltage signals outputted by a control means and adjusting an adjust screw based on the detected voltage signals at the time of air-fuel ratio feedback ...
A carburator for internal combustion engines has a main jet for delivering fuel to be entrained with air as it passes through the carburator to the inlet side of the engine. A throttle valve is disposed downstream of the main jet for controlling the flow of air and entrained fuel. An idl...
The engine can run at the air/fuel ratio of 48 with the super low idle speed of 400r/min smoothly. 发动机可以在空燃比48下稳定运行,并具有400r/min的超低怠速。 参考来源点火室式直喷汽油机燃烧系统及其喷雾特性研究 机械工程 空转 动力与电气工程 无效的 网络...

SIMULTANEOUS CONTROL FOR IDLE REVOLUTION SPEED AND AIR-FUEL RATIO IN INTERNAL-COMBUSTION ENGINE PURPOSE:To simultaneously control the idle revolution speed and the air-fuel ratio by recognizing an engine as a dynamic system and using a state-variable controlling method, estimating the dynamic behaviour...
To quickly reflect the open degree reducing phenomenon with elimination of the deposit to a learning value in the case where an air-fuel ratio by the basic fuel injection quantity at the time of idle operation is displaced to a lean side from the theoretical air-fuel ratio by the predetermine...
A two-stage carburetor having improved cylinder-to-cylinder idle air/fuel mixture distribution is disclosed. The carburetor includes a controlled air leakage which is provided on one side of the idle air/fuel mixture source to balance the leakage of air around the throttle valve in the secondary...
model had better Sauter Mean Diameter (SMD) uniformity than B model,but it had a worse lean blowout performance,and the flow rate in the inner swirler of A model should decrease to establish a low pressure stagnation region which would be helpful to improve the lean blowout fuel air ratio....
