CNG/LPG Engine Control
Both CNG and LPG powertrain systems are cheaper and more eco-friendly in cars than diesel or gasoline systems. Their combustion is comparably cleaner, reducing emissions of particulates and nitrogen oxides. Both fuels are also cheaper than gasoline or diesel. ST offers a strong portfolio of advanced technologies (BCD for combining precision analog, power, digital and non-volatile memory functions; embedded Flash 32-bit microcontrollers for real-time control), coupled with an extensive standard product offering to meet market demands. The block diagram above shows an example of ST’s solution.
