PERFOMANCE BOOST The Freescale* MPXV4115V pressure sensor is the ideal part for automotive vacuum sensing needs such as those found in the brake booster application. Prepared by Marc Osajda Automotive Sensor Marketing Motorola – Toulouse, France Advanced braking systems are becoming increasingly common in today’s automobiles. Higher level systems and technology now being used in “brake assist systems” (BAS) in several European cars, have made it possible for more efficient and intelligent braking systems. A key functional application block found in these braking systems that has advanced with this technology surge, is the vacuum brake booster function. Here are a few driving factors behind the need and use of the brake booster, which helps ensure a safer braking system. Independent Systems: In current gasoline engine cars, the engine’s intake manifold generates the vacuum for the brake booster. This system works fine with one exception. The amount of vacuum in the brake booster is unknown by the braking system. Thus the amount of amplification is also unknown. If heavy braking is needed, there is no possibility for the brake system to interact with the intake manifold if additional amplification is required. The manufacturer’s interest for having the vacuum generated by an auxiliary vacuum pump is that the brake system can manage the amount of vacuum as required, on demand. This in turns gives it the ability to perform amplification on its own, giving it complete independent from the engine’s operating condition. The auxiliary pump is also able to provide higher amounts of vacuum whenever necessary. In situations calling for heavy braking, the pressure will naturally decrease in the brake booster, also causing a decrease in the amplification during braking. With an external pump it is possible to maintain, or even increase the amplification during a heavy braking phase. Smart Safety: Wheel blocking due to high-braking force is controlled by the Anti-Lock Brake System (ABS). However, it has been observed that in many cases, drivers do not...
Vacuum Brake Booster Testing and Diagnosis Vacuum Brake Booster Testing and Diagnosis This procedure will require the use of a hand operated vacuum pump with a vacuum gauge. If you do not own one it can often be rented or borrowed from most “big box” parts stores. (Note: 18”HG is the minimum engine vacuum at idle in gear to effectively operate a vacuum booster 1) Remove vacuum hose from check valve on booster. Place hose from vacuum pump onto check valve and draw booster to 20” of vacuum. 2) Let booster sit with vacuum applied for 5 minutes. If vacuum does not stay steady at 20” it is faulty and needs to be replaced. If vacuum does hold steady at 20” proceed to step 3. 3) With 20” of vacuum in booster depress brake pedal once and release it. The booster should transfer some but not the entire vacuum in reserve. Depending on how hard the pedal is depressed it is normal to see 5-10” of vacuum depleted from reserve. The most important thing is to ensure the booster does transfer vacuum but does NOT transfer the entire vacuum in its reserve. If vacuum remains at 20” OR goes to zero the booster is bad and will need to be replaced. If vacuum transfer is within the above parameter proceed to step 4. 4) Once again draw booster down to 20” of vacuum. Go inside car and depress brake pedal and hold down for 30 seconds. You should see the gauge drop slightly and then hold steady. Vacuum should stay steady as long as you are holding the pedal down. If vacuum drops while pedal is being held down the booster is faulty and will need to be replaced.

Fifty percent less pedal force I n most of the models of the 1950s and 1960s, Mercedes-Benz provided a power brake booster manufactured by ATE. The booster does not pro- vide additional braking capacity, a common misconception, but rather reduces the pedal force required for braking. The power brake is a vacuum-assisted hydraulic component using the pressure difference between engine intake manifold vacuum and atmospheric pressure for its operation. The power unit increases the pressure created physically in the brake master cylinder so that the same braking effect can be produced with less pedal effort. With a brake booster installed, the pedal force required for braking is reduced by 50 percent. The ATE T50 Brake Booster uses vacuum to “boost” the hydraulic brakeline pressure. The booster contains a hydraulic cylinder, a large vacuum piston that presses against the hydraulic cylinder, and a control circuit that regulates the vacuum flow based on brake-line pressures. This technology had been well proven since the early 1900s, and the T50 has been exceptionally reliable over many years of use. The Booster in action The power booster is a very simple design requiring only a vacuum source to operate. In gasoline-engine cars, the engine provides a vacuum suitable for the boosters. Because diesel engines do not produce a vacuum, dieselpowered vehicles must use a separate vacuum pump. A vacuum hose from the intake manifold on the engine pulls air from both sides of the diaphragm when the engine is running. When the driver steps on the brake pedal, the input rod assembly in the booster moves forward, blocking off the vacuum port to the backside of the diaphragm and opening an atmospheric port that allows air to enter the back chamber. Suddenly, the diaphragm has vacuum pulling against one side and air pressure pushing on the other. The result is forward pressure that assists in pushing the input rod, which in turn pushes the piston in the master cylinder. The amount of power assist that’s provided by the booster depends on the size of the diaphragm and the amount of intake manifold vacuum produced by the engine. A larger diaphragm will increase the boost.

INPORTANT SAFETY INSTRUCTIONS USA013-1 WARNING: WHEN USING A CORDLESS CHAIN SAW, BASIC SAFETY PRECAUTIONS SHOULD ALWAYS BE FOLLOWED TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, AND INJURY TO PERSONS, INCLUDING THE FOLLOWING: READ ALL INSTRUCTIONS 1. Keep Work Area Clean Cluttered areas invite injuries. Do not start cutting until you have a clear work area, secure footing, and a planned retreat path from the falling tree. 2 2. Consider Work Area Environment Use extreme caution when cutting small size brush and saplings because the slender material may catch the saw chain and be whipped toward you or pull you off balance. Do not operate a chain saw in a tree unless specifically trained to do so. When cutting a limb that is under tension be alert for spring back so that you will not be struck when the tension in the wood fibers is released. Do not expose chain saw to rain. Do not use chain saw in damp or wet locations. Do not use chain saw in presence of flammable liquids or gases. 3. Guard Against Electric Shock Prevent body contact with grounded surfaces. For example: metal pipes, wire fences. 4. Keep Children Away Do not let visitors contact chain saw. All visitors should be kept away from work area. 5. Store Idle Chain Saw When not in use, chain saws should be stored in a dry, and high or locked-up place - out of the reach of children. When storing saw, use a scabbard or carrying case.
