Vapor Fuel System Design

Although it is highly desirable to keep fuel vapor pressure as low as possible for fire safety reasons and for the sake of fuel system pumpability low vapor pressure also adversely affects engine starting and altitude relight capability.

Vapor fuel system design. The vapor tank is constructed of heavy duty steel or the like to withstand the large vacuum pressure and includes an air inlet valve coupled for. Your present fuel system will not deliver the vapor needed for efficient fuel economy whether fuel injection systems or carburetor. The bulk modulus characteristic is generally not a fuel system design driver. When you re routing fuel line remember that a 90 degree fitting is equal to adding several feet of line to the fuel system.

Page needed there are two types of vehicle emission control systems. Vapor recovery units vrus on storage tanks. Vapor fuel system tom ogle s invention resulted in 1000 increase in mpg his death posted by frank l. Vrus are relatively simple systems that can capture about 95 percent of the btu rich vapors for sale or for use onsite as fuel.

An onboard refueling vapor recovery system orvr is a vehicle fuel vapor emission control system that captures volatile organic compounds voc potentially harmful vapors during refueling. The system operates by using the engine vacuum to draw fuel vapors from a vapor tank through a vapor conduit to a vapor equalizer which is positioned directly over the intake manifold of the engine. Onboard refueling vapor recovery orvr is a vehicle emission control system that captures fuel vapors from the vehicle gas tank during refueling. These vapors are then burned through the combustion chamber during vehicle operation preparing purging the canister for the next refueling event.

Reliable fuel delivery systems for fuel injected cars using a blend of oem and aftermarket products and technologies vaporworx makes standalone simple to use oe reliable and easy to repair fuel delivery systems for a variety of efi platforms. An opportunity as using our design help you take the short cut from such an install in most cases. Aluminum fuel line works great on low pressure applications or you can opt for speedway s blue and black high pressure fuel hose or stainless steel braided hose. Although the original hot vapor engines relied on a carb with no computer modern 21st century fuel injection and computer enhancements could be used to fail safe the engine in event of system.

The orvr and the stage ii vapor recovery system without either of these two systems fuel vapors trapped inside gas tanks would be.
