Abstract

The invention relates to a novel electronic throttle valve body for a diesel engine. The electronic throttle valve body comprises a throttle valve body (1), a throttle valve shaft (2), a throttle valve sheet (3), a position sensor (4), a direct current motor (5), a motor gear (12), an intermediate gear (13), a sector gear (19) and a torsion spring (10), the throttle valve shaft (2) is rotatably mounted in the throttle valve body (1), and the throttle valve sheet (3) is fixedly mounted on the throttle valve shaft (2). The direct current motor (5) is installed on one side of the throttle valve body (1), the motor gear (12) is installed on an output shaft of the direct current motor (5), the intermediate gear (13) is rotatably installed on the throttle valve body (1), the intermediate gear (13) is meshed with the motor gear (12), the sector gear (9) is meshed with the intermediate gear (13), the torsion spring (10) is sleeved on the sector gear (19), and two ends of the torsion spring (10) are fixed on sector gear limiting support legs (19). The gas saving effect is achieved through simple transformation of internal parts.

Description

technical field [0001] The invention relates to the technical field of automobile diesel engines, in particular to a novel electronic throttle body for diesel engines. Background technique [0002] Generally, diesel engines do not have a throttle valve. With the development of intelligent technology, some advanced technology diesel engines (mainly passenger car diesel engines) use throttle valves to control the intake air. The purpose is to improve exhaust emissions and meet emission regulations. Car diesel engines usually use EGR (exhaust gas recirculation) technology, and when diesel engines are partly loaded, the excess air coefficient is very large. (Popular understanding is that the amount of air consumed by burning 1kg of fuel is more than the theoretical air consumption, and the mixture in the cylinder is a lean mixture at this time), so the exhaust gas can be introduced into the intake pipe by increasing the EGR rate to reduce the NOx emission. [0003] In order to...
