HBO - Gas Equipment

We offer gas equipment for cars and trucks and a full range of professional services related to them.

And in all European countries, the popularity of a particular system depends on the manufacturer’s warranty for their product, on access to service and technical support from their representatives, on the quality of the equipment offered, and its prevalence in the region.

HBO - Gas Equipment

There are several types of LPG systems on the HBO market. To classify them, it is customary to use the term “generation”.

Each generation works on its own principle.

To begin with, it must be said that the difference in the systems relates to gas supply elements, as well as the control system. The remaining components (cylinder, gas pipes, filling device) are identical for all generations.

1st generation HBO - Ejector with a register (with electric or vacuum gearbox). The simplest scheme of gas supply to the engine is equipped with an ejector reducer with electric or vacuum control. Next is a simple mechanical dispenser and mixer. Gas is supplied to the intake manifold, to a common receiver.

2nd generation HBO - Ejector with lambda control. The basis of the system is the same as in the first generation, but instead of a simple mechanical dispenser, a stepper motor is installed, the signal to which comes from the controller. The input signals for it are the lambda probe signal and the throttle position sensor. It also has a name, lambda control system.

3rd generation HBO - Gas injection that does not use the gas injection strategy as the basis for calculating gas injection. This system uses a pressure reducer. Gas is supplied separately to each cylinder. Dosed with a special metering device with a stepper motor. It does not use a gasoline injection strategy to calculate the required gas quantity.

4th generation HBO - Gas injection, sequential. When working on gas, the gasoline control unit continues to control the engine, only the signal to the gas injectors is the input signal to the gas control unit. The gas control unit makes its corrections, taking into account the temperature of the gas, nozzles, gas pressure and controls the electromagnetic gas nozzles. Those. the gas control unit is an add-on and all standard engine sensors are used during operation.

More details:

Distributed injection of the gas vapor phase as an alternative fuel system for internal combustion engines, conventionally called the “4th generation HBO system”.

4th generation systems have long been and are quite widely represented in the market of HBO systems throughout the world, including in Ukraine. They are used in the adaptation of vehicles for use as an alternative fuel gas mixture propane-butane or natural gas methane. They are widely used in all injection vehicles, including those with turbo-superchargers equipped with OBD, OBD II, EOBD self-diagnosis systems and comply with strict European emission standards EURO -3, -4, -5.

The principle of operation of HBO 4th generation applies equally to all manufacturers of these systems. It is the same for everyone.

Liquefied gas, coming from the cylinder through the gas-fuel line, through the filter element of the primary gas purification (fuel filter of the liquid gas phase), enters the gearbox-evaporator. Due to the fact that the reducer is connected to the engine cooling system and is heated by coolant passing through its internal water coat, it acts as a gas evaporator, and its internal mechanism regulates the pressure and delivers the vaporized gas further towards the car engine.

Under the influence of heat transfer of the cooling liquid, liquid gas passes from a liquefied state of aggregation to a gaseous one. Then, from the reducer, through the fine-filtering element of the gas vapor fraction (or, alternatively, the gas vapor phase filter), the vaporous gas enters the fuel rail through the fuel hoses in which the gas nozzles are installed.

The on-board computer of the car, based on the information that the designers put in the fuel card of this car, sends certain impulses (signals) to gasoline injectors, which are necessary to create the correct fuel mixture. These signals are intercepted by the electronic control unit (ECU) of the HBO system to carry out the necessary corrections in the adaptation of the gas mixture with respect to the fuel-gas card. After that, the processed signals are sent further, but already to the gas nozzles.

The resulting pulses open the gas nozzles and allow them to supply the necessary amount of gas to obtain the correct air-fuel mixture. Injecting portions of gas through the "gas nozzles" that are installed in the intake manifold, in close proximity to gasoline injectors.

This description, briefly presented in this way, is possible for someone to help understand the strategy of HBO of the 4th generation, if previously it was not fully understood.

Dutch, Polish, Italian, Lithuanian, Russian, Turkish, Korean, Chinese manufacturing companies have saturated the world market for fourth-generation HBO systems; today their number has far exceeded 40.

The various marketing strategies used by the manufacturers of these systems result in a large selection for future customers. Some companies present on the market complete sets of model and universal systems. Others make it possible to assemble the most necessary complete set of a universal system, using elements from third-party manufacturers for this. All this, in the first place, gives companies the opportunity to occupy a specific niche in the market of HBO systems.

And in all European countries, the popularity of a particular system depends on the manufacturer’s warranty for their product, on access to service and technical support from their representatives, on the quality of the equipment offered, and its prevalence in the region.

Our company services most of the systems on the Ukrainian market of gas equipment.
