- Functional Components
These are important fuel- and brake-related parts that support the basic vehicle functions of driving, turning, and stopping. In addition to their reliable quality, we have succeeded in making products that are lighter and more compact, capturing a leading share of the world market.
Fuel Tank Peripheral Parts
1Plastic fuel filler pipes
These pipes convey fuel to the fuel tank. They function for the smooth flow of fuel and to prevent backflow.
2Fuel filler caps
These caps are attached to prevent fuel leakage from the intake port when the gas pump nozzle is inserted, by functioning as a seal.
3Capless device
A device designed to make refueling more convenient by simply inserting the nozzle without opening or closing the filler cap when refueling.
4Fuel hoses and tubes
These rubber and plastic pipes send fuel to the engine and fuel vapor to the atmosphere via the fuel vapor cleaner.
5Cutoff valves
These valves prevent the elevation of pressure inside the tank by releasing vaporized gasoline when the internal temperature rises. The number used on a vehicle has been reduced by raising the ventilation performance with a modified structure, contributing to lighter weight of the fuel tank overall.
6Fill limit vent valves
These valves restrict the amount of fuel when the tank becomes full, functioning to seal and prevent variation in fuel levels.
7Inlet check valve
Check valves prevent fuel from flowing backwards out of the fill tube opening when the tank becomes full.
8High pressure hydrogen tanks
One of the main components of fuel cell electric vehicles (FCEVs). The thickness has been minimized and the capacity increased while maintaining the tank’s compressive strength. The hydrogen storage efficiency is about 10% higher than the previous tank.
Engine Peripheral Parts
9Plastic turbo ducts
These pipes send compressed air to raise engine output. In addition to withstanding high pressure and temperature, they absorb engine vibrations. (Long, complex pipes are blow formed with plastic, reducing weight by about 50 %.)
10Radiator hoses
These hoses connect the engine and radiator for the circulation of the coolant that is needed to cool the engine.
11Noise absorbing air intake ducts
These ducts take in outside air needed in engine revolution. Intake noise is reduced with the use of air permeable members in part of the duct.
12Air cleaner hoses and resonators
Air cleaner hoses are used in providing the clean air needed for engine revolution. Resonators reduce the noise that is generated when air is taken in.
13Engine covers
By covering the top of the engine, these covers make the engine compartment more aesthetically pleasing and reduce noise from the engine itself.
14Plastic water pipes
These pipes are placed around the engine. They include several types with different functions. They are used for air conditioning, oil cooling, turbo cooling, and other functions.
Chassis and Drive Train Parts
15Battery cases
Battery case made of plastic stores multiple batteries
16Brake hoses
These hoses transmit hydraulic pressure in the body-side brake system to the wheel-side brake system. They are flexible and highly durable so that they can follow the movement of the wheels.
17Constant velocity joint boots
These boots have a cylindrical, bellows shape and are used to cover constant velocity joints, which turn and flex. They keep joint lubricating grease in and water and dirt out.
18Oil pumps
These pumps suction up and circulate oil to reduce friction in the transmission gears and bearings. Leveraging our plastic precision molding technology, we have made the gears and other oil pump components of plastic and reduced mass by about 30%.
