His innovative designs focus on improving the efficiency and performance of engine systems.

Latest Patents

One of his latest patents is a phase angle detector. This device computes the phase angle of individual impulses imparted to the crankshaft of an internal combustion engine. It includes means for computing the sine and cosine functions of each torque impulse in response to the instantaneous rotational velocity of the engine's crankshaft. Additionally, it detects changes in the crankshaft's rotational velocity at the beginning and end of each torque impulse. The system also corrects the value of the generated sine function based on the difference in the crankshaft's rotational velocity during the torque impulse. Ultimately, it computes the phase angle of the torque impulse from the cosine and corrected sine functions.

Another notable patent is the phase angle modification of the torque amplitude for fuel distribution. This fuel distribution control system detects the instantaneous rotational velocity of the engine's crankshaft to generate a torque impulse amplitude signal and a phase angle signal. It features an amplitude correction circuit that adjusts the torque impulse amplitude signal based on the phase angle signal. The system generates an amplitude error signal for each corrected torque impulse and accumulates these signals to create individual fuel correction signals for each engine cylinder. These fuel correction signals are then combined with the fuel quantity signals generated by a fuel control computer, ensuring that each cylinder contributes equally to the total output torque of the engine.
