Abstract:
An internal combustion engine comprising:an engine block defining a plurality of cylinders; a plurality of pistons with a piston received in each cylinder; a plurality of pressure sensors with a pressure sensor configured at each cylinder to detect cylinder pressure; a crankshaft having an encoder, the crankshaft driving the pistons; a crankshaft sensor for detecting a position of the crankshaft, allowing determination of the position of each piston within its cycle; and a controller configured to determine a pressure within each cylinder and the position of each corresponding piston within its cycle, and further configured to control the engine in real time based on a series of cylinder pressures and corresponding piston positions including determining a net work for the cycle for each piston based on the cylinder pressures and corresponding piston positions.
