车型:日产风度 A31,1992年产,直列六缸发动机,直接点火。故障现象:凉车时一切正常,达到正常工作温度后,发动机抖动,且怠速不稳(在1000～1500r/min 上下游动),加速不良,排气冒黑烟,耗油量较大。故障排除:该车凉车正常,热车发抖,看来温度是一个极其重要的影响参数。用一个变化范围是5k Ω的滑动电阻模拟水温传感器,当调整
Model: Nissan demeanor A31, 1992, inline six-cylinder engine, direct ignition. Symptoms: cool car when all normal to reach the normal operating temperature, the engine jitter, and idle slow down (at 1000 ~ 1500r / min up and down), poor acceleration, exhaust black smoke, fuel consumption. Troubleshooting: The car is cool, the car shivers, it seems that temperature is an extremely important influence parameter. Use a sliding resistor with a variation range of 5kΩ to simulate the water temperature sensor when adjusted
