engine (presumably a Type P75), with no exhaust gas recirculation, as: Hydrocarbons and nitrous oxides: 2.85 grams per kW hour

(2.1 grams per hp hour) Carbon monoxide: 2 grams per kW hour

This compares with the predicted emission requirements (in California) of 4.76 and 13.6 grams per kW hour (3.5 and 10 grams per hp hour) respectively.

Solar Stirling Engine Basics Explained

The solar Stirling engine is progressively becoming a viable alternative to solar panels for its higher efficiency. Stirling engines might be the best way to harvest the power provided by the sun. This is an easy-to-understand explanation of how Stirling engines work, the different types, and why they are more efficient than steam engines.
