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 its 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 gas equipment systems on the LPG market. For their classification 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 systems relates to the elements of the gas supply, as well as the control system. The remaining components (cylinder, gas pipes, filling device) are identical for all generations.

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

2nd generation HBO - Ejector with lambda control. The basis of the system is the same as in the first generation, only instead of a simple mechanical dispenser, a stepper motor is installed, the signal to which comes from the controller. 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, which does not use the strategy of gasoline injection as the basis for calculating gas injection. This system uses a pressure reducer. Gas is fed separately to each cylinder. It is dosed with a special metering device with a stepper motor. It does not use the strategy of gasoline injection to calculate the required amount of gas.

4th generation HBO - Gas injection, sequential. When working on gas, the engine continues to control the gasoline control unit, only the signal to the gasoline nozzles is the input signal to the gas control unit. The gas control unit makes its own corrections, taking into account also the temperature of the gas, nozzles, gas pressure and controls the electromagnetic gas nozzles. Those. the gas control unit is a superstructure and all the engine sensors are involved in the operation.

More details:

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

Systems of the 4th generation have long and fairly well represented in the market for HBO systems worldwide, including in Ukraine. They are used in the adaptation of vehicles for use as a propane-butane gas mixture or natural gas methane as an alternative fuel. They are widely used in all injection vehicles, including those with turbo-blowers, equipped with OBD, OBD II, EOBD self-diagnostic systems and meet the strict European emission standards EURO -3, -4, -5.

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

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

Under the influence of heat transfer from the coolant, the liquid gas changes from a liquefied aggregative state to a gaseous state. Next, from the reducer, through the filter element of the fine purification of the gas vapor fraction (or otherwise, the gas vapor phase filter), the vaporous gas enters the fuel hoses into the fuel rail, in which gas nozzles are installed.

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

The resulting pulses open the gas nozzles and allow them to apply the necessary amount of gas to obtain the correct air-fuel mixture. Injecting portions of gas through the “gas jets” that are installed in the intake manifold, in the immediate vicinity of gasoline nozzles.

This description, briefly presented in this way, may help someone to understand the 4th generation HBO strategy, if it was previously not completely clear.

Dutch, Polish, Italian, Lithuanian, Russian, Turkish, Korean, Chinese manufacturing companies have saturated the global market for the 4th generation HBO systems, their number has now far exceeded 40.

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

And in all European countries, the popularity of a particular system depends on the manufacturer’s warranty for its 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 serves the majority of systems represented on the Ukrainian market of HBO.
