4 Vehicle Exhaust System Safety Tips

4 Vehicle Exhaust System Safety Tips

A properly functioning car exhaust system is critical toward keeping the environment clean, reducing noise, as well as preventing a deadly build up of carbon monoxide [CO] inside of your car. You can stop problems from occurring if you keep in mind the following four safety tips.

1. Annual inspection. If you own the correct equipment [such as a lift or jacks] you can perform a visual inspection yourself. Things to look for: corrosion, loose mountings, leaking joints, damage to various parts including the catalytic converter, muffler, pipes, and other exhaust components. Many garages and retail establishments offer free exhaust system inspections as well if you prefer to leave it up to a mechanic. Tip: Always check your exhaust system immediately after bottoming out from a pothole or running over road debris. Do not wait for your annual inspection; inspect it right away.

2. Keep windows cracked open. Carbon monoxide can build up in the cabin of your car without warning. You can't see it and by the time you realize its effects it may be too late. A slightly opened window will help gathering poisons to leave your car's interior. This is especially important to do if you are stuck in traffic.

3. Station wagon precautions. If you own a station wagon and you leave the tailgate down while driving, make sure that windows or vents are open.

4. Open up the garage door. Letting your vehicle run inside a closed garage can be deadly. Fumes will quickly accumulate in the garage and spread to the remainder of the house if you have an attached garage. If you must run your car inside of the garage, vent it by opening up the garage door. Always keep the door from the garage to the rest of the house closed when your car is running inside of your garage.

If you determine that your exhaust system does need maintenance, you can do the work yourself and save plenty of money. Top performing exhaust system brands include Bosal Exhaust, Dynamax Exhaust, Gibson Exhaust, Flowmaster Exhaust, Magnaflow Exhaust, Remus Exhaust, as well as others. Selecting the right system for your car can help you reduce noise, increase torque, and free up horsepower. Above all, a well fitted, properly installed system will protect the environment both inside and outside of your vehicle.

Understanding Fuel System Subaru WRX

Understanding Fuel System Subaru WRX

One of the keys to achieving the right balance of power is the fuel for a certain amount of air. Showing too much or too little fuel in an engine, which delivers the power, the poor economy and a big question mark against his long life. The main task of the engine tuner to ensure that the engine management system has been programmed to deliver fuel in the right quantity at any time.

Fuel mixture is measured in units of either oxygen or fuel-air(AFR). Also referred to as either lean (small amount of jet fuel) or rich to mention regular (large quantities of jet fuel). What is the right mixture of fuel and air? Although there is no such thing as an absolute all areas of recruitment, the generally accepted "golden rules" of the fuel mixtures:

1 At low power outputs (no increase)-catalyst-equipped vehicles, a fuel mixture of lambda need 0.99 (14.64 AFR) for the best mix of fuel and emissions control is the goal when the OE is working inClosed-Loop. Improvements in fuel savings alone can out of fuel mixtures are made to Lambda 1.05 (AFR 15.4 to 1), but this is done at the expense of the cat converter and exhaust gas temperatures will increase in cruise.

2 medium-power outputs (the transition between on and off boost) provides the best performance at around lambda 0.89 (AFR 13.1 to 1) is reached.

3 The power of high performance, it is interesting because this is the area where the greatest potential for engine damage.Version that I have for the stock motors with internal running about 1.2 bar of boost pressure is usually a good reliable service to Lambda 0.78 (AFR 11.5 to 1) VI. At the same boost pressure, and internal stock Subaru WRX Version VII and new models have the cylinder head combustion chambers of a completely different combustion properties and distribution of fuel than the previous model, revised and dictated a lot of fuel mixtures richer around lambda 0.75 (AFR 11, 0 to 1) or lower is best accomplishedMakes it safe.

Typically, air-fuel ratio to be slightly edited for a small increase in power for motors with forged pistons, which is diminished due to their greater strength and heat resistance than OE cast pistons.

Measure fuel mixtures

There are only two ways to fuel mixtures to examine closely the preferred method is to use a broadband high-quality air-fuel ratio meters with five-wire Bosch LSU Lambda. This type of sensor andInstrument can accurately measure fuel mixtures of lambda 0.69 (AFR 10.1 to 1) to 1.30 Lambda (AFR 19.1 to 1) and beyond. Hence the name of the sensor to broadband.

An alternative method for vehicles with compatible flash control unit, fuel mixtures can be read directly from the data stream ECU with Delta Dash, with few exceptions. The OE-oxygen sensor can "see" lean, but can not measure fuel mixtures richer in oxygen 0.76 (AFR 11.2). In addition, a higher rate of storage, sensorPositioning is a problem, as the pressure between the engine and exhaust turbocharger causes a marked reduction in the precision of the sensor.

Any other method of measuring fuel blends as a good DIY meters, reading tea leaves or consulting a psychic have no place in modern high-performance engine tuning.
