Off-road vehicles with a 2L-T type or 2L diesel engine, in general,fit the electric plug inside the cylinder. the glow plugs 35 is controlled by the relay 33, relay coil 33 is controlled by the warm-up timer 37. Warm-up timer work when plug 38a installed in the cooling system inputs the water temperature. When the water temperature is above 5 ℃, if the ignition switch is switched on, preeat indicator light will flash about 38 (about 0.3S), which means that can be started directly; if the water temperature is below 5 ℃, the preheat light 38 will stay on for an period of time (about 18S), until the temperature of warm-up plugs inside the cylinder reaches 800 ℃ or so and lights is off, which shows the vehicle can be started. 70 light-duty off-road vehicle also is equipped with emission control systems. When the water temperature is low, the fuel will have poor atomization, incomplete combustion production is excessive. Emission controller 46 will control the throttle idle switch electromagnetism valve 44, while make the cold mixture heater work and heat up atomization.
