Latest Patents

One of Assanis's latest patents is for a hybrid powertrain system using free piston linear alternator engines. This innovative system includes reciprocating free-piston internal combustion engines, each equipped with a linear alternator device designed to generate electric power. A control module plays a crucial role by determining mechanical and electrical power demands based on an operator's torque request and the state of charge of an energy storage device. The control module effectively operates the torque machine to generate output torque in response to mechanical power demands while also managing the internal combustion engines to produce electric power as needed.

Another notable patent is a method and apparatus to determine the magnitude of combustion chamber deposits. This method allows for the dynamic evaluation of combustion chamber deposits (CCD) in controlled auto-ignition engines. It involves in-situ assessment of the thickness of CCD using a sensor that monitors combustion in a homogeneous charge compression ignition engine. The system includes a temperature sensor that tracks combustion chamber conditions and utilizes a peak combustion temperature measured at a specific crank angle to determine a CCD parameter. Additionally, an in-cylinder pressure monitor can be employed to assess the combustion chamber deposit parameter based on the crank angle location of peak in-cylinder pressure.
