Latest Patents

Among Sahara's latest patents is a cutting-edge **Diesel engine control system and control method**. This invention enables accurate fuel injection by overcoming variations in injector performance that may arise from differences among individual injectors or changes due to aging. The system includes an injector designed for direct fuel injection into the combustion chamber, an injection quantity controller to manage the fuel injection quantity, an estimator to ascertain the optimal electrical current supply period for achieving stable combustion, and a control data correcting device that adjusts the controller's data based on the estimated supply period.

Another notable patent is the **Intake system for diesel cycle engines**. This inventive design incorporates a timing valve positioned within the intake system. During the engine's starting and warm-up stages, particularly under cold conditions, the timing valve opens at the end of the intake stroke. This design increases suction pressure in the combustion chamber, allowing intake air to enter at high speed, further compressing the air and augmenting its temperature. The valve operates in response to the chamber's suction pressure, opening only when it surpasses a predetermined threshold.
