Inventor: ZHANG HONG
IPC: F02M26/00
Filed: 1998-11-06
Abstract: According to the inventive method, an internal combustion engine is operated in the stratified charge operation and a base value for the NOx crude emission is determined which depends on the amount of fuel (MFF) injected into the cylinders of the internal combustion engine and the speed (N) of the internal combustion engine. A correction factor is added to the base value.

Title: Electric generator drive assembly uses Earth's gravity, hydraulic pump, counter weight and controller for causing flywheel to reciprocate and rotate for generating electricity
IPC: H02N11/00
Filed: 1999-03-12
Abstract: A 300 Kg flywheel in the form of a gearwheel is mounted on a metal tube by ball bearings. The metal tube has a circular opening at its upper end for receiving a hook connected with a 500 Kg counterweight and a hydraulic pump by a cable rope. A controller, the hydraulic pump, and Earth's gravity cause the tube to reciprocate together with the flywheel which moves up and down and rotates for driving an electric generator. A controller disengages the hook from the opening of the tube which, then, together with the flywheel, moves downward by Earth's gravity. At the same time, the hydraulic pump operates to repel the counterweight upwards causing the hook to follow the tube's downward movement until it reaches the bottom where the pump stops, the controller engages the hook with the tube, the counterweight falls down due to Earth's gravity pulling the hook, the tube and the flywheel move upwards until the hook reaches the top. The cycle is repeated for continuous generation of electricity.

Abstract: The invention relates to a method for synchronised ignition in an internal combustion engine with a crankshaft sensor and a device for detecting smooth running. The aim of the invention is to provide a method for synchronised ignition which does not require a camshaft sensor. After the engine has started, ignition takes place in all of the upper dead centres (OT's) in at least one cylinder, the time of ignition being offset by a certain value each time that the crankshaft passes through 720 DEG . The effect of offsetting the time of ignition is determined by the device for detecting the smoothness of running. Ignition is assumed to have occurred in the area of the upper dead centre in which the ignition time is offset when the smoothness of running is modified above a predetermined limit value or is assumed to have occurred in the area of the upper dead centre in which the ignition time is not offset when the smoothness of running is not modified above a predetermined limit value.
