Vehicle ignition system Renault 19

Ignition system — design description
Ignition system components located around the ignition module 1 - distributor cap with electrical wires and distributor rotor; 2 - contact connection to the pulse sensor winding; 3 - contact connection for positive "+",...

Ignition system device
The ignition module is combined with the ignition coil into a single unit. The left picture shows a 1.7-liter "F" engine; the picture on the right shows a 1.4-liter type "C" engine. 1 - contact connection of the pulse...

Safety precautions when working with ignition lEZ
Most often, poor ignition system operation is caused by poorly connected or oxidized contact connections. The same applies to the knock sensor (1) - between cylinders 1 and 2 in the cylinder head (left 1.8 liter, right...

Ignition interlock
The ignition module and control unit are inevitably damaged if the engine is cranked with the high-voltage central wire removed. Therefore, to carry out certain work, it is necessary to block the ignition. This can be...

Troubleshooting the ignition system
You will not be able to fix control unit malfunctions yourself. Failures may affect the vehicle's performance, as the emergency program ensures that the ignition is not completely turned off when certain data is lost....

Ignition coil
Ignition coil contacts 1 - "+" terminal; 2 - "+" terminal for noise suppression capacitor; 3 - "–" terminal; 4 - high voltage contact. How the ignition coil works is described at the beginning of the chapter. It...

Checking the ignition coil
The spark plug wires on the 16-valve Renault 19 are well secured and completely protected from vibration. This reduces the likelihood of a malfunction due to spark plug wires. If oil or water gets on the wires or tips...

Ignition distributor
The figure shows the order in which the high-voltage wires are connected to the distributor cap: on the left is a type "C" engine; on the right is the ignition distributor of a 16-valve engine. All Renailt 19 engines...

High voltage wires
The connecting wires of the ignition distributor to the spark plugs usually do not present any problems. If you need to replace the high-voltage wire, try to buy the original wire - it has the required length and is...

Firing order
The high-voltage wiring diagram shows the firing order. The engine on the left is an "F" engine, the engine on the right is a "C" engine. To better understand the firing order, cylinders 1 through 4 are numbered. The...

Checking spark plugs
The Renault service plan includes replacing the spark plugs or at least checking them every 10,000 km. We recommend checking and adjusting them. Only if you drive short distances on a regular basis should you change the...

Spark plug characteristics
Combustion heat: the spark plug gap must be adjusted to the combustion chamber temperature created in the engine. This quality is called combustion heat. Its index indicates what temperature the spark plug can...

Recommended spark plugs
The spark plugs listed in the following table meet all recommendations. Since other spark plugs may be installed, it is recommended to use only the spark plug type specified on the valve cover sticker. Incorrect spark...

Troubleshooting the ignition system
Before you start troubleshooting using this table, you must be sure that the fuel supply is perfect and the petrol injection system is working properly. In addition, we assume that the engine has no mechanical damage....

Preheating device
Cold Engine Starting Device Diagram 1 - preheating device control device; 2 - high pressure fuel pump (HPFP); 3 - engine; 4 - glow plugs; 5 - lever for normal and accelerated idle.; 6 - full load micro switch...

Glow Plugs — Removal and Installation
Inside the glow plug tubes that enter the swirl chamber, there is a glow plug spiral coated with an insulating compound. It must heat the igniter when heated to a temperature above 1000°C. Only then can a cold diesel...

Troubleshooting the Preheater
If one of the glow plugs is defective, it is noticeable mainly on a cold engine. While the fuel in the other cylinders ignites immediately, the cylinder with the defective plug starts much later. The engine initially...
