Product Line

The Air Flow Sensor (MAF) is located in the intake air stream and measures the mass of air entering the engine. The hot wire component of the MAF cools when air mass flows past. The electronic circuit component measures this change in temperature and converts it to a voltage or frequency signal. This signal is sent to the engine control unit to determine how much fuel to deliver to the engine so the vehicle can maintain optimal performance. Hitachi Automotive Systems Americas, Inc.’s MAF accurately controls the engine’s air/fuel ratio for improved fuel economy and reduced emissions.

The Hitachi Automotive Systems Americas, Inc. designed air bypass valves have precise response time and flexible flow capability to maintain constant system pressure. They create a safer driving experience by suppressing backfire during deceleration and virtually eliminating the chance of hydro-lock. Designed utilizing advanced technologies and quality materials, it will ensure reliable and durable performance.

The electronic throttle body (ETB) is a main part of an electronic throttle control (ETC) system. The ETB controls the volume of air flowing into the engine. It features a butterfly valve which opens and closes according to a signal from the engine control unit.

Instead of a traditional throttle body with an accelerator cable, Hitachi Automotive Systems Americas, Inc.’s ETB utilizes a microcomputer to control the valve opening quickly and precisely. Precision is essential to keep engine torque at a constant level when changing the air/fuel ratio. A more accurate ETB translates to improved fuel economy and emissions performance.

An ignition coil is an induction coil that transforms the 12-volt current from a battery into the high-voltage current required by spark plugs to ignite the combustible gas. The ignition coil consists of a primary coil and a secondary coil, each with a different number of wire turns. The primary coil generates a magnetic field with the battery voltage and by using this magnetic field; the secondary coil will have tens of thousands of volts of induced current. Hitachi Automotive Systems Americas, Inc.’s ignition coil is designed to be closer to the spark plug, providing the most efficient spark and reducing the need for spark plug wires.

Hitachi Automotive Systems Americas, Inc. oil pumps are vital to protecting engine components from frictional wear and overheating. Hitachi oil pumps ensure sufficient lubrication and smooth oil circulation. Oil lubricates moving engine parts to allow them to operate smoothly with less resistance and friction. A well lubricated engine increases the odds of a longer service life from its parts. The oil pump also helps disperse engine heat by providing a steady flow of oil and lubricating metal engine parts as they work and carrying heat away from the combustion area.

With modern automobiles replying more and more in computers (ECU) to more efficiently control the cars functions, sensors have become vital to your car running efficiently. Hitachi’s sensor line supports accurate measurement for reliable engine performance. Accurate measurements ensure your car is running efficiently which optimizes fuel economy and performance. Hitachi Automotive Systems Americas, Inc. sensors will help your car's ECU monitor vital parameters such as Air Intake Temperature, Camshaft/Crankshaft Position, Knock Sensor, Crankshaft Angle, Pressure Sensor, Throttle Position.

The Water Pump is a main part of a cooling system in automobile. Cooling the area around the cylinders is critical to the life of your engine. At the heart of the cooling system, Hitachi Automotive Systems Americas, Inc.'s water pump delivers the crucial element to maintain the engine's temperature and prevent seizing. The water pump is responsible for pumping coolant throughout the vehicle's cooling system to keep things at the right temperature.

Valve Timing Control (VTC) system is the combination of VTC and Solenoid Valve (SOL/V). VTC continuously varies valve timing with engine speed, temperature, and load of engine. Valve timing has been fixed by opposing requests of various engine operations. However, VTC achieves continuous and optimum valve timing in all gasoline engine operation.

Engine Control Unit(ECU) computes the required information of engine speed, temperature, and accelerator opening, and sends the control signal to Solenoid Valve. Oil pressure controlled by Solenoid Valve continuously controls VTC.
