Problems solved by technology

This function requires the driver to manually turn the key to the ON position. From the time the driver turns the key to the ON position until the heating is over, the driver needs to wait for a certain period of time before starting the vehicle. In this way, it cannot be started quickly. Thereby reducing driving comfort, convenience
And as the temperature decreases, the heating time calculated by the engine control module will further increase

Embodiment Construction

[0026] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0027] A kind of preheating method of ethanol fuel engine, such as figure 2 shown, including the following steps:

[0028] First, judge whether the car key is inserted into the key hole, if not, start the remote control preheating, the steps are as follows:

[0029] (1.1) The preheating signal transmitting device sends a preheating request signal; in this embodiment, preferably, the preheating signal transmitting device is a remote control key, and the wireless unlocking signal for remote unlocking is used as a preheating request signal, so that , the car remote unlocking device and the preheating signal transmitting device can be combined into one, which greatly facilitates the driver's operation.

[0030] (1.2) The signal receiving device receives the request signal in the step (1.1); in the present embodiment, preferably, the signal receiv...

Abstract

A preheating method for an ethanol fuel engine, comprising: sending, by a preheating signal sending device, a preheating request signal; receiving, by a signal receiving device, the preheating request signal; and processing, by an engine control device, the preheating request signal, and then starting a heating device to heat, so that the ethanol fuel engine can be preheated in advance before a driver enters a vehicle, thereby realizing quick start of the engine, saving the waiting time of the driver and improving the driving convenience and comfort.

Description

technical field [0001] The invention belongs to the field of engine control, in particular to a method for preheating an ethanol fuel engine. Background technique [0002] Because the chemical and physical properties of ethanol fuels are different from traditional gasoline fuels, ethanol cannot volatilize below 12°C, which will make it difficult for ethanol engines to start cold at low temperatures. [0003] At present, in order to solve the problem of cold start of ethanol fueled engine, someone proposed a cold start method for flexible fuel vehicles, the method is as follows: figure 1 As shown, the battery is mainly used as the power supply, and the fuel is preheated before injection by using a heating injector to increase the temperature of the fuel before injection to improve the atomization effect of the fuel. The system requires the driver to turn the key to the ON gear first, activate the engine control module, and then judge whether to heat and control the heating f...
