A method of controlling an internal combustion engine includes determining the pressure within the cylinder with a pressure sensor which samples at specific positions of the piston indicating the properties of the thermodynamic cycle. The engine is controlled and operating condition diagnosed in real time based on that series of cylinder pressures at corresponding piston positions.

1. 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.
