In-cylinder pressure sensor.


Kavlico, Moorpark, Calif., a usiness unit of Custom Sensors & Technologies (CST), has developed an in-cylinder pressure sensor designed to optimize engine combustion and increase fuel efficiency while reducing emissions. The sensor assists with the timing and delivery of the fuel by providing accurate pressure information to the engine control unit to control fuel injection pulses, enhancing combustion, control and cylinder pressure management while reducing gaseous and particulate emissions all the while improving fuel consumption, the company said.

The sensor utilizes a thin film titanium oxynitride sense element in an all-welded, hermetically sealed, stainless-steel housing. Kavlico said the package design is suited for hostile environments. Pressure ranges are available from zero to 2900 psi through zero to 4350 psi.

The sensor operates on 5 Vdc and provides a linear amplified analog output of 0.5 to 4.5 Vdc proportional to pressure as standard with other custom output options. The sensor is impervious to electromagnetic interference (EMI), Kavlico said.

The sensor also has a small probe OD of 8 mm and the probe can be specified up to 3.9 in. in length. The sense element is located at the tip of the sensor, for a highly accurate and fast output response time, the company said.
