The present disclosure provides a piston, comprising: a skirt having an upper body portion; and a crown formed on the upper body portion by an additive manufacturing process, the crown including at least one air gap formed and positioned to reduce heat transfer from combustion to at least one cooling gallery formed in the piston.

An opposed-piston engine includes an electronic sensor located in a charge air channel, at position between an outlet of a charge air cooler and an air intake component that distributes charge air to cylinder intake ports of the engine. The electronic sensor is disposed to measure a rate of mass airflow between the outlet of the charge air cooler and the intake component and generate electronic signals indicative of the rate of mass airflow from the charge air cooler. A control mechanization of the opposed-piston engine is electrically connected to the electronic sensor for controlling air handling devices, fuel provisioning devices, and/or EGR devices in response to the electronic signals.

A combustion pre-chamber device for a spark ignition internal combustion engine is configured to engage a spark plug and be mounted to a cylinder head in communication with a combustion chamber of a cylinder of the engine. The combustion pre-chamber device includes a number of bores that open at an outer surface thereof that extend into the body and receive a coolant flow to provide cooling for a combustion pre-chamber of the combustion pre-chamber device.
