Winter affecting fuel consumption for several motives

Car engine car diagnostic tool function necessary to get regular temperatures (80 ~ 90).
If the temperature is also higher, the engine cooling process can immediately transform the cooling water, boost the heat, get rid of excess heat; Conversely, cutting down the circulation of cooling water to sustain the necessary temperature.
To reach the primary elements of the cycle instantly transform the engine temperature sensor sensor, thermostat valve thermostat and magnetic fan. Cold start, the magnetic fan is stopped, the thermostat valve is from the down state, the engine coolant while in the engine water jacket only in tiny cycles, easy to heat, even though personal computers had been affected temperature sensor temperature index, will probably be issued to increase fuel injection, growing the idle valve opening instruction, increase the engine pace is conducive to allow the engine to heat up rapidly; temperature is standard, the fuel injection quantity and idle valve opening are restored to normal. When the temperature exceeds 80 to 90 degrees (on the automobile slightly unique), the thermostat valve is opened, the engine water jacket by means of which coolant flows through the radiator thermostat valves larger radiator circulation of air produced from the motor vehicle flow, away quite a bit of heat, to maintain standard temperature on the coolant.
Slow or even Launch X431 Master end, but when the pace isn't going to stall, no flow of air to assist dissipate heat, the engine will swiftly heat up, then issued a directive towards the magnetic temperature sensor aids radiator cooling fan begins.
In winter, the engine requires is heat rather then heat! Winter resulting from the affect of your air movement, the engine temperature is just not easy to retain at 80 to 90 degrees, the engine will boost the injection amount and adjust the ignition advance angle to help keep the temperature, whilst the thermal efficiency is significantly gasoline being a hot day. Further, so as to keep the ordinary speed you'll unknowingly increase the throttle opening degree. These will enhance fuel consumption.
Winter open air will enhance fuel consumption
Engine in Launch Creader VII buy to maintain the temperature in winter, primarily in compact cycles; And any time you open the sizzling air, the automobile promptly by way of heatercore cold surface, in fact, for that engine cooling system which increases an effective heat sink! Its function could be imagined.
