Q&A

• What are the prospects for mass production of the opposed piston engine?

  Nine automakers have signed on as development partners for the opposed piston diesel engines, and at least one automaker has started implementing tooling for producing them in greater volumes. Viewers are encouraged to share their thoughts on the engine's pros, cons, and potential for mass production.

• What were the test results and findings on the efficiency of the opposed piston engine?

  Test results from 2012 demonstrated high and consistent thermal efficiency across various loads and rpm. Recent studies from 2017 supported these findings, showing the potential for high efficiency in different layouts, especially with three cylinders.

• How does the engine's port system optimize airflow?

  The engine's ports open exhaust and intake ports at specific times for efficient gas exchange. The three-cylinder setup is considered ideal for efficiency, avoiding gaps in exhaust delivery and reducing residual gas.

• What is the design of the opposed piston engine?

  The engine has two pistons moving towards each other, no valve train, and uses two crankshafts geared together to supply power to a single output shaft. It has a 2.7 liter 3-cylinder configuration, generating 270 horsepower and 480 pound-feet of torque through efficient design.

• How does the unique opposed piston engine operate?

  The engine operates as a two-stroke engine, with combustion occurring when the pistons meet at top dead center. It has no valve train, and fresh air is pumped in through ports on the bottom of the cylinder, while exhaust is pumped out through ports on the top of the cylinder.
