Ignition system — design description Elements of the ignition system located around the ignition module 1 - ignition distributor cover with electrical wires and ignition distributor rotor; 2 - contact connection to the winding of the pulse sensor; 3 - pin...
Ignition system device The ignition module is integrated with the ignition coil into a single unit. The left figure shows a 1.7-liter engine type «F»; in the right picture is a 1.4-liter engine type «WITH». 1 - contact connection of the pulse...
Safety precautions when working with lEZ ignition Most often, the cause of poor operation of the ignition system is carelessly connected or oxidized contact connections. The same goes for the knock sensor (1) - between cylinders 1 and 2 in the cylinder head (left...
Ignition lock The ignition module and control device will inevitably be damaged if the engine is cranked with the high voltage center wire removed. Therefore, to carry out certain work, it is necessary to block the ignition. This can...
Troubleshooting in the ignition system Faults in the control unit cannot be repaired by yourself. Malfunctions can affect the driving performance of the car, as the emergency program ensures that the ignition is not completely switched off when certain data...
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. She receives...
Checking the ignition coil The spark plug wires on the 16-valve Renault 19 are well secured and absolutely vibration proof. This reduces the chance of a malfunction due to spark plug wires. If oil or water gets on the wires or on the tips...
Ignition distributor The figure shows the sequence in which the high voltage wires are connected to the ignition distributor cover: on the left, the engine type «WITH»; on the right is the ignition distributor of a 16-valve engine. All...
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 get the original wire - it has the required length and is...
Ignition order You can find out the ignition order from the high voltage wire connection diagram. Shown on the left is an engine «F», on the right - type engine «WITH». To better understand the firing order, cylinders 1 to 4 are...
Checking spark plugs Renault's service plan calls for changing the spark plugs, or at least checking them every 10,000 km. We recommend checking and adjusting them. Only for constant driving for short distances should the spark plugs be...
Characteristics of spark plugs Calorific value: The gap at the spark plugs must be adjusted to the temperature of the combustion chamber generated in the engine. This quality is called the heat of combustion. Its index indicates what temperature the...
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. Unsuitable 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 mean that the engine has no mechanical damage....
Preheating device Cold start device diagram 1 - device for controlling the preheating device; 2 - high pressure fuel pump (injection pump); 3 - engine; 4 - glow plugs; 5 - lever for normal and accelerated x. X.; 6 - full load microswitch...
Glow plugs — removal and installation Inside the glow plug tubes that enter the swirl chamber is a glow plug coil coated with an insulating compound. It should heat the igniter when heated to temperatures above 1000°C. This is the only way to start a cold...
Troubleshooting the preheater If one of the glow plugs is damaged, then this is noticeable mainly on a cold engine. While the fuel in the remaining cylinders ignites immediately, the cylinder with a bad spark plug starts much later. The engine does...
