Problems solved by technology

However, when good startability cannot be obtained by turning the crankshaft, the driver cannot judge whether the cause is a system problem such as an engine failure or an environmental condition.

Embodiment Construction

[0038]FIG. 1 is a schematic configuration diagram of a start information display device including an internal combustion engine of a vehicle to which the present invention is applied. The engine 1 is configured to be able to use a mixed fuel mixed with various fuels, for example, to operate by burning a mixed fuel mixed with ethanol and gasoline. In the intake pipe 2 that introduces air to the engine 1, an air filter 3, a throttle valve 4, and an injector 5 are installed from the upstream side, and the inflow of the intake air purified by the air filter 3 is adjusted by the throttle valve 4. The fuel injected from the injector 5 is mixed and supplied to the engine 1 . A three-way catalyst 8 is provided on the downstream side of the exhaust pipe 7 of the engine 1 to purify components such as HC, CO, and NOx in the exhaust gas. The injector 5 is connected to the control device that controls the operation of the engine 1, that is, the ECU (Electric Control unit) 20, and injects ...

Abstract

The invention, with a simple and inexpensive structure, provides a device by which a driver can be aware of the situation prior to starting up an engine when confirming the starting-up performance of the engine is worsened. In the vehicles including the engine which can use a fuel mixed by a plurality of fuels, the device for displaying starting-up information includes an air temperature detector(13) which detects the temperature of the external air or the air inhaled by the engine; a starting-up display (35) which displays the information about the starting-up performance of the engine prior to starting up the engine, according to the temperature of the external air or the inhaled air detected by the air temperature detector.

Description

technical field [0001] The present invention relates to a start information display device for a vehicle including a fuel-mixed engine capable of using a mixture of multiple fuels. Background technique [0002] In recent years, vehicles equipped with internal combustion engines (engines) capable of using not only gasoline currently used as fuel but also gasoline mixed with various fuels such as alcohol (methanol or ethanol) have been put into practical use. However, gasoline and alcohol differ in latent heat of vaporization, ignition point, etc., and when alcohol having poor low-temperature startability compared with gasoline is supplied to the storage tank, the startability decreases at low temperatures where the ambient temperature is low. For this reason, a kind of fuel switching device of the engine is proposed, and its structure is to separate and independently set up two storage tanks dedicated to gasoline and storage tanks for alcohol or mixed fuels, and when starting...
