STARTING CONTROL SYSTEM FOR WORK VEHICLE

摘要

PROBLEM TO BE SOLVED: To prevent a work vehicle from slipping down when starting on a hill by reducing time lug arose when braking is released until engine starts. SOLUTION: In this work vehicle, an engine with a throttle valve driven by a DC motor 63 is mounted. Further, an oil temperature sensor 68 for sensing engine temperature and throttle valve opening calculation means 51 are provided. The throttle valve opening calculation means 51 calculates an opening of a throttle valve when the vehicle starts based on the engine temperature and activates the DC motor 63 for adjusting the opening of the throttle valve to the calculated one. The throttle valve opening calculation means 51 also controls the opening of the throttle valve when the engine starts in a cool state so that the engine enters a complete explosion state rapidly.
