Types of systems - generations


Various fuel systems used in petrol engines of vehicles require selection of a proper generation and type of gas system. In the terms of installation of LPG systems, there are five generations of propane-butane fuel supply systems. The main factor that decides about correct selection of LPG system is the type of petrol fuel system used in given car.


1st generation - is designed for cars equipped with an engine, in which a carburettor or a fuel injection system has been used, without a lambda sensor (fuel systems in older cars); it is the cheapest type of fuel system with manual switching from petrol to gas (carburettor) or automated switching (fuel injection system).

 

2nd generation - is designed for cars equipped with an engine, in which a single- or multipoint fuel injection system with a lambda sensor and a catalytic converter is used. Switching from petrol to gas is automatic and depends on engine r.p.m.

 

3rd generation - is designed for cars equipped with an engine with multipoint fuel injection system, a catalytic converter and a plastic air intake manifold. Currently this generation is no longer offered due to its replacement by the 4th generation.

 

4th generation - the most common LPG system on the market, which consist in injection of LPG in the gaseous phase. Each gas injector is assigned to a single cylinder and switching from petrol to gas is fully automatic, smooth and unnoticeable to a user. On the other hand, for cars equipped with an engine with direct fuel injection (e.g.: FSI, GDI), there has been created a system that is dedicated to a given type of engine and was developed especially for it. It is used in cars with 4-cylinder engines, naturally aspirated or turbocharged.

 

5th generation - the most advanced of all currently used LPG systems, which is dedicated to specific car models. A distinguishing feature of the system is sequential injection of LPG in the liquid phase, pumped under pressure into the combustion chamber. The injection takes place with the use of the original petrol injectors and a high-pressure pump, so gas injectors and a gas reducer have been eliminated.
