Latest Patents

Chikara Dodate holds a patent for a "Control device for internal combustion engine." This invention involves a main injection and a sub-injection that injects a minute amount of fuel during a short driving time. The device conducts checks to ensure that the minute amount of fuel is injected accurately. During specific cycles, particularly at cold starting when catalyst warm-up control is performed, the main injection is omitted. Instead, a checking injection corresponding to the sub-injection is executed. The injection conditions of the in-cylinder injection valve are made uniform between the checking injection and the sub-injection. The actual fuel amount injected is calculated based on the air-fuel ratio of exhaust gas and the in-cylinder air amount, which is then compared with the theoretically expected fuel amount.
