“…When this process continues, the volume of hydrogen gas will increase with time. Thus the assumption of hydrogen gas volume produced/accumulated will be the unit of time t = y cm 3 and the average rate of reaction of hydrogen gas is y = volume/time or by using the y cm 3 = piston syringe [3].…”

“…Atmospheric pressure of around 6.8 kg per square inch (psi) causes pressure reduction in the carburettor when the piston starts moving down (BDC) [2]. As a result, this movement causes pressure differentials, and this allows air to enter the combustion chamber into the cylinder until the pressure in the two halves becomes equal [3]. The high airflow through the carburettor will cause fuel to flow out into the venturi and mix with air by gravity.…”

“…The oxidation of carbon atoms in the fuel (gasoline) to carbon dioxide (CO2) cannot be completes owing to a lack of oxygen atoms. Creep fire from the spark plug also cannot reach the full space of the combustion chamber owing to a lack of oxygen to support combustion [3]. This often happens when the engine temperature is below the working temperature (80 °C), especially when starting the engine and then heating it up in the cold condition.…”

The fossil fuel price crisis and emissions control in the transportation sector in Malaysia have become national issues, especially in the transportation sector. As an alternative, using hydrogen mixed with gasoline fuel in conventional combustion engines is a very effective way of improving engine performance and emission control. Generating hydrogen via a chemical reaction between hydrochloric acid and aluminium is a new approach in this study. This methodology has been tested through the mixture application (G + H2) in 10-year-old motorcycles (gasoline) with a modified conventional carburettor engine. The testing of engine performance by chassis dynamometer was done at three levels of experiments: L0: 0 Amp load, L1: 1 Amp load, and L2: 2 Amp load for different engine performances, particularly in identifying quality improvements through the brake thermal efficiency. The study found that the average increase in brake thermal efficiency was 23% higher in the (G + H2) engine compared to gasoline only. The results of this study have proven that the use of hydrogen (Al + HCl) in the stoichiometric ratio has helped to increase combustion efficiency, especially when the oxygen content in the fuel mixture ratio is not adequate during the stroke of power. The successful reduction in fuel consumption, increased engine performance, reduction of pollution and the system's ability to meet the basic needs of the internal combustion engine cycle can be beneficial to the development of the automotive industry, particularly in the transport sector.

“…In previous papers by our group we have reported on the modifications carried out to adapt the gasoline SI engine of a Volkswagen Polo 1.4 to be fueled with hydrogen [38]. A gasoline carbureted engine-generator set was also converted to an electronic fuel-injected power unit capable to operate bi-fuel (hydrogen-gasoline) [39]. Later on, a commercial Volkswagen Polo 1.4 A04 vehicle was adapted to run bi-fuel, that is, with gasoline or hydrogen as desired by the driver [40].…”

“…Hybridization with an internal-combustion engine (ICE) based on hydrogen (H 2 ICE) could help to increase autonomy and reduce costs of production comparatively to the others' type of hybridization: battery-fuel-cell, etc. [4]. The genset efficiency depends on the output power and the engine speed [5] [6].…”

This paper presents a Linear Quadratic with Integrator (LQI) controller for a hydrogen genset (internalcombustion combustion engine generator) which is used to extend electric vehicle range. Since the genset efficiency depends mostly on generator rotor speed and produced power, a maximum efficiency tracking method is required. The optimal operating conditions provided by the efficiency tracking module must be imposed to the genset. Thus, we proposed a LQI controller for dynamically driving genset operating conditions toward the optimal one. This controller is based on a state space model in which the genset parameters are identified offline using the Least-Square (RLS) algorithm. Preliminary evaluation using real genset data with this type of controller demonstrated the effectiveness of the proposed approach.
