Basic Automotive Electrical Ignition

Conventional Ignition system

How to ignition of fuel at motor fuel divided into 2 types:

Ignition of its own                                   Ignition by electric sparks

(Diesel motor)                                                    (Motor gasoline)

Diesel motor

 Compressed air with a high compression pressure

• 20-40 bars (2-4 MPa) temperature rise 700 - 9000C

The fuel is sprayed into the combustion chamber

• Direct ignition occurs / combustion

Motor gasoline

 Air + fuel mixture compressed with low compression pressure

• 8-13 bar (0.8 to 13 MPa) temperature rise 400 - 6000C

sparkplug ignition sparks occur / combustion

Conventional ignition systems on motor gasoline there are 2 kinds:

1.Sistem battery ignition

2. Magnetic ignition system
 
How to Boost Voltage

 12 Volt                                                                  5000 – 25000 Volt

Battery voltage (12 V) was raised to high voltage 5000 - 25 000 volts using a transformer (coil).

Basic Voltage Transformation

Voltage transformation based on the principle of magnetic induction

a) The magnetic induction

If the magnetic digerak moving near the coil, then:

• There was a change in magnetic field

• Incurred voltage

Voltage is called "Voltage Induction"

b) Transformer

If the primary connection is connected to an alternating current transformer - back then:

• There are changes in electrical current

• There was a change in magnetic field

• There induksii voltage lights

c) Comparison of Voltage

Comparison of the voltage proportional to the ratio of the number of windings

• The number of winding induced voltage slightly smaller

• The number of induced voltage winding many large

d). Transformation with direct current

What if given a direct current transformer?

• The transformer may not work with direct current, because:

• flows remain

• no magnetic field change occurred

• There is no induction

How to change the magnetic field?

By giving the switch on the primary connection

If the switch is opened / closed (on / off), then:

• Primary Flow disconnected - broken

• There is a change in magnetic field

• There was an induction

How Pneumatic Governor Work?

Governor pneumatic vacuum in the venturi to work depends. Vacuum has arisen to regulate engine speed = 40-80 milli bar. Pneumatic governor can regulate each round (round of idle - max rounds) and Diesel motors are used in small sizes that have a high rotation. Pneumatic governor is divided into two main parts:

a. Venturi section mounted on the engine suction channels.

b. Membrane block sections mounted on injection pump

1. The main parts

1.Air filter
2. Venturi (main and auxiliary)
3. Throtel valve
4. lever setter
5. Vacuum channel
6. Spring regulator
7. Vacuum chamber
8. Membrane
9. Atmospheric space
10. Ventilation of the atmosphere
11. Trunk control

2. How it works pneumatic governor

a. position start

 

Engine off, throtel fully opened, the vacuum zero. Regulator at maximum position rod.

b. idle position

Throtel on retaining the idle rotation speed big air and high vacuum regulator shaft attracted towards the stop / bit. Decrease engine speed vacuum regulator shaft pushed down towards the maximum. Rev the engine, climbed up the vacuum, and so on.

c. The position of maximum rotation and restriction

Throtel on retaining the maximum rotation, a small vacuum regulator shaft driven toward the maximum volume. The maximum rotation is reached, when the power vacuum and a spring is proportional regulator. If the engine turns up again, then the air velocity increases up = vacuum up, control rods are interested in towards the stop / bit, no reduction in the number of injections = maximum rotation in the regulation

d. How to turn off the motor

1. Mechanically

Control rod is pulled toward the mechanical stop

(see picture)

2. pneumatically

With additional throtel, throtel regulatory vacuum in a very large, regulators are interested in towards the stem stop

3. additional venturi



The main functions:
• Adjust vacuum in the vacuum chamber by the injection pump airflow
• Prevent the motor turning round

How it works:

At the time of spin flipping machine, suction channel to channel exhaust. Flue gas velocity in the venturi major addition, the vacuum in the vacuum of space is also large, regulators are interested in towards the stop rod = engine died.

4. ancillary equipment

In the round of idle, less rapid cycle regulation, control rod movement from maximum to minimum is too long so the spin machine can not be stable. To prevent this additional equipment installed.

a. Additional spring round of idle with the screw setter

function:

Reduce cycle regulation that is too large so that the idle rotation can be stable Atmospheric space associated with air filters so that air flow does not affect the regulatory process.

Examples: isuzu

b. Additional spring round of idle with the switch nok 

 

In the round of idle switch nok, an additional spring pressure so that the idle rotation cycle regulation that is too large can be minimized. Throtel When opened, the switch peak despite additional spring is not functioning anymore.

c. vibration dampers






with spuyer                              With rubber dampers

Function: damping vibrations in the vacuum caused by the membrane blocks the air velocity in the venturi. Spuyer Diesel motors are used in a number of cylinders 6 and 8 cylinder Gap function to avoid vibration caused by control rod lever membrane. Rubber silencer muffled thud function caused by axial movement of the lever system idle lever membrandengan

Governor Centrifugal / Mechanical

Centrifugal governor used primarily on large diesel motors. Governor is mounted on the type inline injection pump. In the implementation, the centrifugal governor is divided into two types:
a. Centrifugal type governor RQ / RQV
b. Centrifugal type governor RS / RSV

Readmore → Governor Centrifugal / Mechanical

Governor Centrifugal type RSV

RSV type centrifugal governor is a governor that can regulate each engine speed (revolutions idle up to maximum rotation). Letter V (verstell) means the setter / transfer. In the centrifugal governor there is only one type of RSV as a regulator of the tensile spring mounted outside the centrifugal weights.
1. The main parts

1. Spring start
2. setter lever
3. Pull lever
4. Lever between
5. Spring regulator
6. Additional spring (idle) 7. Regulator lever
8. Bearing inter-
9. Centrifugal weights
10. Swing lever
11. Trunk control

2. The workings of the centrifugal type RSV governor

a. position start

At the time the engine has not been alive, control rod position is always at the start because the pull of spring start. Thus the machine can be more easily turned on even though the lever setterin idle position.


b. idle position

Lockout lever on round idle position. Regulators are interested in a littlespring-loaded centrifugal weights depending on the opening round of the idleand the power of the regulator spring. Rev the engine up, opened the centrifugal weights, the volume of injection is minimized. Engine speed goes down, the centrifugal weights injection volume enlarged close. Can be stabilized so that the idle rotation, then to regulate the springmounted additional rounds for idle round.

c. Regulation on the middle rounds 

Lockout lever on the middle lap position, the spring attracted a strong regulator, the regulator rod moves toward the maximum, the centrifugal weight is still slightly open. Thus a large volume injection / lot, the engine turns up. Open centrifugal weights. If the centrifugal force greater than the strength of the spring. Thus, regulators are interested in towards the small injection volume / least until there is a balance between the centrifugal force with the power of the regulator spring.

d. The position of maximum rotation and restriction 

Lockout lever on the regulator interested in the position of maximum spring full. Injection volume and a lot of high rpm centrifugal weights open. The maximum rotation can be achieved if the centrifugal force is proportional to the strength of the spring regulator. Engine speed increases up to open stronger centrifugal weight control rod attracted towards the stop .
