CNG and LPG automotive sensing solutions
Sensata Technologies is one of the world’s leading suppliers of sensing, electrical protection, control and power management solutions across a broad array of industries and markets.
Our products improve safety, efficiency and comfort for millions of people every day in automotive, appliance, aircraft, industrial, military, heavy vehicle, heating, air conditioning, data, telecommunications, recreational vehicle and marine applications.
Alternative fuels are playing a bigger role in engine design, and create some unique challenges for engine control systems. Compressed Natural Gas (CNG) and Liquefied Petroleum Gas (LPG) engines and its infrastructure are steadily gaining position around the world. They offer improved fuel diversity and emissions benefits - not to mention tax and mobility incentives in some areas.
Sensata Technologies has hundreds of millions of pressure sensors in the field today.
Most are in harsh automotive applications. We have experience in CNG and LPG powered cars, trucks, buses and forklifts for years. Whether low pressure for the fuel rail, high pressure for tank pressure, or even combined pressure + temperature, Sensata has a wide, proven portfolio. Our CNG and LPG products meet regulations set by the International Organization for Standardization (ISO) as well as by the United Nations Economic Commission for Europe (UN ECE) and bear these organizations’ approval marks and certification numbers. More than 65 countries worldwide have adopted ISO 15500 and UN ECE R110 for CNG and R67 for LPG.
Sensata Technologies’ products are developed together with OEMs to the highest performance requirements and made to the highest quality standards.
The Fuel Rail sensor measures the absolute pressure of the fuel at the inlet of the injectors to optimize fuel metering and to control combustion for improved emissions and engine performance. Whether CNG or LPG, it is conventional to measure both pressure and temperature, and the CP+T package combines both readings in one convenient robust package.
The pressure measurement from the Regulator or Tank Valve application is used to calculate the amount of fuel in the tank for dashboard fuel gauge indication. It replaces more traditional electro-mechanical devices and its accuracy can even help to detect possible leakage in high pressure CNG systems.
