Throttle Body Assemblies For Sale In order for your engine to run, it requires air and fuel, with a spark to ignite the compressed air-fuel mixture. A throttle controls the amount of air that is drawn into the system. Common throttles use a butterfly valve but can use a pinch valve or barrel-type. This valve is part of the throttle body assembly. Engines with fuel injection use a throttle body assembly that is often located between the air filter assembly and the intake manifold of the engine. A throttle valve is also used in carbureted engines. As you depress the accelerator, or throttle pedal, on your vehicle the valve opens to allow more air to flow. As more air enters, the amount of fuel increases to meet the required ratio. Electronic Control Units (ECU) Some vehicles use direct linkage from the accelerator pedal to the throttle to control the amount of air entering the system. Electronic throttle control systems use a motor to control the throttle linkages. In this system, the accelerator is connected to a sensor that sends information to the ECU. The ECU adjusts how much the throttle will open based on this signal. Throttle Body Injection (TBI) TBI systems are similar in design to carburetors. This version uses one or more fuel injectors set on top of the assembly. The injectors spray fuel through the valves, along with the air, for compression and combustion. As a note, Ford uses the term CFI instead of TBI. Multi-Point Fuel Injection (MFI) throttle bodies In an MFI system, the throttle body only controls the air that enters the system. The fuel injectors are separate from the assembly. Idle Air Control (IAC) Some engines use a […]
Timing Belts For Sale
Timing Belts For Sale An internal combustion engine contains a number of parts that move and spin at tremendous speeds. In order for the engine to run properly, these moving components must be synchronized, much like the gears in a clock. The job of synchronization falls on the timing belt, and if the timing belt fails, serious damage to your engine can result. Unlike the belts that drive your alternator or air conditioning compressor, the timing belt is not visible upon opening up the hood. It is located behind the accessory belts, guarded by plastic or metal covers. As such, accessing the timing belt usually requires quite a bit of time and disassembly. The typical timing belt requires that you remove, at a minimum, one of the front tires, the crankshaft pulley, the accessory drive belts, and the protective cover or covers. It is also common to have to remove engine mounts, the valve cover or covers, some of the belt-driven accessories, the air box, and/or other components as well. This is why it costs so much to have the job done at a garage. At $75.00 per hour for labor, removing all of this stuff and putting it all back into place once the new belt is on can put a comma in your repair bill. This is also why changing the timing belt yourself can save you so much money, because the lion’s share of the cost is labor. Timing belt replacement intervals vary from vehicle to vehicle. The standard used to be every 60,000 miles. However, improvements in technology and in belt materials have extended the change interval on some vehicles to as much as 90,000 miles or more.

Turbos for Sale
Turbos for Sale Engines burn a mixture of fuel and air. The fuel may enter the combustion chamber through fuel injection or carburetion. Air is normally drawn into the chamber through the air filter by atmospheric pressure. A turbo charging system creates a higher amount of air, or pressurized air, to be sent into the chamber. The basics of turbos The gases that are expelled in the exhaust system of an engine are wasted energy. Turbos make use of normally discharged gases to turn a turbine. The turbine forces more air into the engine of the vehicle. When there is more available air, more fuel can then be used while still maintaining the fuel to air ratio of the engine. The higher amount of fuel produces a larger explosion from combustion. This results in more power being delivered by the engine. As the piston returns to the top of the cylinder to begin a new cycle, unburned fuel and burned gases are pushed out through the exhaust system of the engine. On the exhaust side, spent gases are directed over a turbine wheel. The force of the exhaust turns the turbine. This is similar to the movement of blades on a windmill. A shaft connects the output of the turbine to the engine and a compressor or air pump. The compressor is turned by the shaft, creating compression and forcing the additional air into the combustion chamber. This type of system is designed for additional power. It also improves fuel efficiency when used to make the most out of wasted energy in the exhaust gases. More manufacturers are using turbine systems to maximize fuel economy without sacrificing power. An additional benefit is a reduction in […]
