The brake booster utilizes the difference between the engine vacuum and the atmospheric pressure to generate a power boost. Therefore, the brake booster function can be checked by conducting the following Read more Function Check of Brake Booster
What is a Proportioning Valve?
1. General
The proportioning valve (P valve) is placed between the brake line master cylinder and the rear wheelÅfs wheel cylinder. This device obtains proper braking force to shorten the braking distance Read more What is a Proportioning Valve?
Types of P Valve
1. Dual P Valve
The dual P valve is used in diagonal brake piping in FF vehicles. Basically, it may be considered as a pair of P valves operating side by side. Each of the two P valves operates Read more Types of P Valve
ABS with EBD
The EBD control utilizes ABS, helping realize the proper brake force distribution between front and rear wheels in accordance with the driving conditions. In addition, during cornering braking, it also Read more ABS with EBD
BA (Brake Assist)
Sometimes people who are not used to driving or people who panic easily even if they are used to driving do not step down hard enough on the brake pedal during emergency braking to realize the full performance Read more BA (Brake Assist)
VSC (Vehicle Stability Control system) Overview
While the ABS and TRC are mainly used to stabilize brake operation and accelerator operation during braking and acceleration, the VSC ensures the gsteering and direction stabilityh of the vehicle. The Read more VSC (Vehicle Stability Control system) Overview
Skid Control ECU
1. TRC control
The hydraulic pressure that is generated by the pump is regulated by the master cylinder cut solenoid valve to the required pressure. Thus, the wheel cylinder of the drive wheels is controlled Read more Skid Control ECU
TheTRC and VSC Brake Actuator 2 of 2
2. Pressure increase (High pressure)
In contrast to the time when the pressure is low, when the pressure is high, the booster pressure that is applied to the rubber reaction disc increases. Accordingly, Read more TheTRC and VSC Brake Actuator 2 of 2
Elements of a Gasoline Engine
All gasoline engines mounted on Toyota automobiles are four-stroke engines. Four-stroke engines operate by continuous and regular repetition of the following sequence:
1. Intake stroke
2. Compression Read more Elements of a Gasoline Engine
Three Elements of Gasoline Engines
1. Good air-fuel mixture for automobiles
(1) Gasoline is vaporized and sufficiently mixed with air In order for gasoline to completely burn, it must be sufficiently vaporized and mixed with air.
