Accelerator-pedal module The electronic control adjusts the optimal mixing ratio between air and fuel as well as the optimal time of injection. Read more. General-purpose actuator The air supply for the motor is just as important for the combustion of the air-fuel mixture as the fuel itself.

Grinding machines that support workpieces with a combination of 2 shoes and a magnet or combination of 1 shoe and 2 rollers for optimal grinding. TVG-series grinding machines that achieve accurate and efficient grinding with a compact body and a simplified setup change process and vertical grinding machines that support very large workpieces with a machinable diameter of up to 3, mm. Vertical centerless-type grinding machines that can machine workpieces in many ways with a single chucking action.

This model is a vertical-type profile grinding machine designed to accurately and efficiently machine out-of-round shapes such as inner and outer diameters of cam-shaped parts. Accurate and efficient honing machines that have been completely sophisticated though our automobile-component production lines. Capable of machining all materials used in the IT industry including semiconductors, solar cells, LEDs, and power semiconductors.

We propose high-productivity machines such as a multitasking machine capable of both of boring and honing. Product line of machine tool components, such as wheel heads, perfectly fit for your production activities.

Wheelheads Wheelheads. Remote Monitoring Remote Monitoring. Toward our own business field. The surface treatment technology is very promising. TiC It's most suitable for processing of high tensile strength steel by the high hardness and the slippery nature.

C-TiCN Ideal for stainless steel molding high seizure resistance. Inspiring-TiC The high hardness and slipping are the coating by which wear resistance could excel close adherence very highly well. CrN The coating by which wear resistance could excel resin mold release characteristics highly. P-TiCN High-wear-resistance coating perfect fit for cutting tools and forging dies.

TiN Wear resistance and corrosion resistance to excellent coating. Low-temperature CrC Corrosion resistance and the coating which could excel release characteristics. The fuel rail is the long, round metal bar that runs along the top of the injectors and is held onto the manifold with a few bolts. Adding Larger Fuel Injectors Increasing the injector nozzle size will result in increased fuel delivery all the time. As "Langer" mentioned in engine basics, a rich fuel mixture results in power loss.

Therefore, increasing the nozzle size could have a negative effect on performance and economy. Fuel Mileage. Bigger injectors would equal more fuel, which means less fuel mileage or fuel economy , right?

Not necessarily. There is a common misconception that the larger the fuel injector , the more power they create. Fuel injectors do not create horsepower , they support horsepower. The larger the flow rate, the more horsepower they are able to support. As a result, most vehicles have OEM fuel pressure regulators to keep the required constant pressure in the fuel rail. We recommend cleaning fuel injectors at least every 36 months or 45, miles.

Consider it a tune up for your fuel system- it's really amazing the difference people experience after having a fuel injection and throttle body cleaning on a car that has gone more than 60, miles without those services. When it comes to turbo cars, you'll need to upgrade your fuel system with performance injectors and a performance fuel pump. Otherwise, the injectors won't be able to flow enough fuel to the engine to make your car run the way you want it to.

You should also match your performance fuel injector to your specific engine. Larger throttle body and injectors A larger high- performance throttle body will deliver more horsepower. Depending on what type of engine you have, you can gain as much as more horsepower and comparable torque. There is a catch, however. Also remember that a larger throttle requires higher-flow fuel injectors. A larger turbo or supercharger will move more air into the engine.

The fuel side is a bit more complicated and has two parts. Larger fuel injectors can deliver more fuel to the engine, but a larger fuel pump is also needed to supply the injectors. So at 20psi of boost the fuel pressure should be 63psi. Engine stalling might occur as the fuel rail pressure sensor goes from bad to worse.

You will be driving and then suddenly, your engine will stall. It may also stall while idling.
