Compared with liquid fuels, CNG produces far fewer CO 2 emissions and combusts virtually particle-free. This makes the fuel even more environmentally friendly. The natural-gas injection valve injects natural gas compressed natural gas — CNG at system pressure into the intake manifold. The fuel-rails provide the CNG fuel with the required pressure from the pressure regulator up to the natural-gas injection valves.
Natural gas compressed natural gas — CNG stored under high pressure is supplied by way of the pressure regulator in the fuel rail.
The electronic engine control unit is the central control unit and the heart of the engine management. Bosch continues to systematically develop the CNG powertrain for passenger cars and commercial vehicles, including systems and components for the fuel supply, fuel injection and engine management. Bosch also offers a solution for non CNG-specific components for gasoline engines.
The comprehensive portfolio of CNG technology applies for many different gas engines and vehicle types: from small cars to heavy-duty commercial vehicles. Other key factors are extensive system expertise, consulting services and proven standard components. Compressed natural gas is supplied by way of the fuel line from the high-pressure tank to the pressure regulator and is regulated there.
The high-pressure sensor reliably monitors the pressure in the high-pressure circuit. From the pressure regulator, gas is applied with a system pressure of usually under 10 bar is supplied to the CNG fuel rail and is temporarily stored there. The medium-pressure and temperature sensor from Bosch monitors the pressure and the temperature in the fuel rail. Depending on the engine requirements the CNG injector NGI2 dose the natural gas with highest precision into the intake manifold.
From there the gas-air mixture is sucked into the cylinder. This mixture is then ignited by the spark plug in the cylinder. Bifuel engines can be designed on the basis of gasoline direct or intake-manifold fuel injection. Bosch systems can be used in both turbo and naturally-aspirated engines and are able to powertrain vehicles with low-pressure and medium-pressure system designs.
To ensure that components from Bosch are future proof, they are designed for use in oil-free gas. Biogas can also be used with the latest standard components. Using a two-step chemical process, renewable methane eCNG can be produced from water, CO2 and regenerative electricity. This reduces the CO2 footprint of the vehicle. With that development in mind, eCNG can be called the first eFuel in automotive series production. Are you interested in our solutions? Please don't hesitate to contact us!
We will be glad to help you. The gasoline port fuel injection is the most popular drive system for gasoline engines worldwide. Purely electric propulsion is efficient does not generate any local CO2 emissions and delivers full torque right from the start. These components make CNG the primary fuel for your vehicle with gasoline as the back-up fuel. A fuel selection switch will be installed usually on the dashboard that will allow the driver to manually select either CNG or gasoline.
CNG storage cylinders will also be installed underneath the vehicle for vans and pickup trucks, or in the trunk for cabs and other cars. The CNG will then pass through a fuel filters then to High Performance Fuel Injectors, finally on to the intake manifold to be introduced for combustion. Having a dual fuel system will ensure adequate fuel reserves between natural gas fills.
Exhaust system: The exhaust system channels the exhaust gases from the engine out through the tailpipe. A three-way catalyst is designed to reduce engine-out emissions within the exhaust system. Fuel filler: A nozzle from a fuel dispenser attaches to the receptacle on the vehicle to fill the tank. Fuel injection system: This system introduces fuel into the engine's combustion chambers for ignition. Fuel line: A metal tube or flexible hose or a combination of these transfers fuel from the tank to the engine's fuel injection system.
