Here are the terms on the engine and engine parts that feel we need to know:
1. DOHC
Double Over Head Camshaft (also called twincam). 2 (two) camshaft within 1 (one) cylinder head. In the east, was applied to the s515i using injection technology in combustion systems.
2. SOHC
Single Over Head Camshaft. A camshaft in a cylinder head, on the east was applied to the S515 which uses carburetor technology in combustion systems.
3. ECU (DOHC)
Engine Control Unit, also known as EMS or Engine Management System, is an electronic system that controls several aspects of the machine. ECU determines the amount of fuel, ignition timing and several other parameters that are monitored by sensors which are machined to provide a mass flow signal or resistansi.It lies approximately below the tape car (inside cabin).
4. TPS (DOHC)
Throttle Position Sensor, is a sensor used to monitor the position of the throttle on the engine. This sensor is usually in the form of a potentiometer which varies the resistance value according to the position rather than flap. Signal is then sent to ECU as an input to control the time of ignition and injection timing.
Usually located on the throttle body butterfly spindle (throttle flap), so it can directly monitor the position of the opening of the flap.
5. ATS (DOHC)
Water Temperature Sensor, the sensor which is used to calculate the temperature of incoming air. Located on the elephant's trunk.
6. MAP Sensor (DOHC)
Manifold Absolute Pressure Sensor is a pressure sensor that instantly generate information that is used to calculate the air density (water density) and determine the Air Mass Flow Rate, which is then used in the ECU to calculate the amount of fuel flow, the appropriate.
Other data necessary for the vehicle which doubles the MAP system is a Speed Density, Cycle engine, and air temperature. It lies above the AC pipes (engine room), the shape of a black box the size of a matchstick.
7. WTS (DOHC)
Water Temperature Sensor, the sensor which is used to calculate the temperature of cooling water circulating inside the machine. Located near the transmission.
8. ATS (DOHC)
Water Temperature Sensor, the sensor which is used to calculate the temperature of incoming air. Located on the elephant's trunk.
9. ISC (DOHC)
Idleup Speed Control, is the part that serves to keep the iddle / spin machine when another load on, such as AC and Power Steering. Serves also as an automatic choke on a cold engine, the carburetor timor (SOHC) means more or less the same functions known as the Vacuum tripple Act.
10. HLA (DOHC / SOHC)
Hydraulic Lash Adjuster, is the part that serves to keep the slit valve opening / valve in order to stay 0:00 mm, with the existence of this part, we will never timor set of valves. Located in the cylinder head, the number 16 for the DOHC, 8 for the SOHC.
11. Ignition Timing / Ignition Time (DOHC / SOHC)
Is the time of ignition (spark / ignition) that occurs in combustion chamber (during the power stroke) relative to piston position and crankshaft angular velocity.
Setting the right will affect engine durability, keiritan fuel and engine performance. For the standard DOHC Ignition 8 + / - 2 degrees. For the standard SOHC Ignition 4 + / - 2 degrees.
12. Timing Belt (DOHC / SOHC)
Part that serves to control the timing of the valve. Timing belt connects the crankshaft to the camshaft which then controls the valves open and close it. It's on the left side cylinder head, the shape of a toothed belt on the inside, the timing belt replacement is recommended to replace all its idler.
13. Radiator (DOHC / SOHC)
Is a tool that was designed as a heat exchanger or to transfer heat energy from one medium to another medium for cooling or heating purposes.
