Dr. Nikolay Shkolnik, an entrepreneur and inventor, and his son Alexander, a
PhD student at the Massachusetts Institute of Technology, have invented a
patented novel engine architecture, which will enable the engine to reach 50%
fuel efficiency and drastically reduce pollutant emissions, compared to
existing engines. The engine is based on a patent-pending "High Efficiency
Hybrid Cycle" (HEHC) thermodynamic cycle, borrowing elements from Otto, Diesel,
Atkinson, and Rankine cycles. Several critical design features make the
LiquidPiston engine architecture both versatile and capable of outperforming
conventional engines on all parameters.
The result is an engine with the following characteristics:
(with respect to Otto or Diesel engines of similar power specifications)
-
Significantly improved engine efficiency, reaching 50%
-
Reduced size and weight by 50%
-
Reduced parts count by 85%, which leads to: lower cost of production and
greater reliability
-
Reduced NOx emissions by 70%
-
Reduced CO2 emissions by 50%
-
Low friction design leading to long life
-
Decreased maintenance requirements: no oil or spark plug changes required, ever
-
Less noise, due to low pressure exhaust and absence of poppet valves
