CNG Regulator
SQT has a wide range of CNG regulators having output pressure from 2 bar g to 9 bar g.
Primary Function: The primary function of a CNG regulator, also known as High Pressure Regulator (HPR) or High-Pressure Regulator Valve (HPRV), is to reduce the pressure of CNG, coming from high-pressure CNG storage cylinders to lower-pressure CNG supply toward the engine. All the CNG regulators work on a single-stage pressure reduction principle, which results in better accuracy and consistency.
The expansion of high-pressure gas (CNG) to low pressure creates a very large temperature drop. In order to prevent freezing inside the regulator and creating a blockage, heated engine coolant must be circulated through the regulator.
All CNG regulators come with pre-approved automotive regulations.

Fuel Injectors
SQT has a state-of-the-art injector manufacturing facility, and has manufactured over 1 million injectors.
SQT offers a wide range of injectors, compatible with multiple fuels such as CNG, LNG, LPG, hydrogen, etc. with wide operating pressure range from 1.5 bar g to 8.5 bar g. We offer different types of injectors, based on gas inlet type (i.e. side feed and top feed) and based of operating circuit (i.e. (peak & hold type, and saturated type).
Primary Function: The primary function of a fuel injector is to inject desired quantity of fuel into the intake manifold or port, just before the inlet valve. The amount of fuel injection is being controlled by ECU (Engine Control Unit).
All Injectors come with pre-approved automotive regulations.
