Intake / Carburetors
The engine intake system is responsible for filling the cylinders with
a fuel-air mixture. The better the intake system is made the more filling it is
possible to get. The main components of this system: intake receiver (another name - intake manifold), throttle (other names - throttle pipe, flap), low-resistance (other name
- zero-resistance air filter), carburetor (another name - carb), multi (other name - throttle unit,
A LADA receiver is responsible for filling the cylinders. Its shape, volume, as well as the intersection of the intake pipes and the receiver greatly affect the behavior of a LADA engine. A LADA throttle controls the amount of air entering the intake tract. The intake manifold on which the LADA carburetor is installed has a completely different design. In a LADA injection engine, the air-fuel mixture passes through the shortest path in a channel to the LADA valve seat, and in an engine with a LADA
carburetor, the air-fuel mixture passes through the entire collector.This is the main reason of the difference in intake manifolds. The standard LADA receiver is designed for maximum performance in
the low and medium speed range of the LADA engine, so using it in tuning
will be somewhat inappropriate. The same applies to the LADA throttle, its
throughput may not be enough for a high powered engine. A standard LADA carburetor very often becomes a spare part that does not allow you to reveal the full potential of the engine. LADA receivers, which are installed for engine tuning, have different designs. they differ in length of the channel, volume of the receiver, shape of the channel and location of the throttle.
By the length of the channel, you can understand what range of engine operation the receiver is configured for. With a long intake channel, the receiver is set to a low and medium range of engine operation, with a short one - to a higher speed range. The volume of the receiver must not be less than the volume of the engine. The location of the throttle and the volume of the receiver determines how evenly the air distribution between the cylinders will be. In any case, whether you have a LADA carburetor or a LADA receiver installed, replacing them with tuning ones is only required when the LADA engine is thoroughly refined. Today it has become very fashionable to install zero-resistance filters on both injection and carburetor engines. Remember that filters require frequent cleaning. Otherwise, the valvea and piston rings may suffer from sand.
