Commercial Engine Company

The Commercial Engine Company was located in Los Angeles, just south of where the City Hall now stands. Commercial built engines of their own design and catered to the Southern California marketplace.

This 25 horsepower engine was built circa 1915. It was used to run a compressor in an oilfield in Carbon Canyon near Brea, California. It is equipped with the optional "natural gas fuel mixer." Natural gas is an abundant byproduct of oil production, and as such, it was used almost exclusively in powering engines in the oilfields.

A feature characteristic of this Type C Commerical is the use of individual pushrods for the actuation of each of the engine's components. Separate pushrods are used to actuate the mechanical oiler, magneto, throttle, exhaust valve and intake valve.
