The fuel tank is part of the Evaporative Emission Control System (EVAP) that prevents vapour loss
The Jeep Grand Cherokee is a powerful and robust vehicle, offering impressive capabilities for adventurers and road-trippers alike. The fuel tank in the Jeep Grand Cherokee is more than just a container for fuel. It is an integral part of the vehicle's overall performance and efficiency.
The fuel tank in the Jeep Grand Cherokee is officially known as a fuel supply tank. Its primary function is to supply fuel to the engine, ensuring that the vehicle has the power it needs to tackle various terrains and conditions. The fuel supply tank also houses other critical components, such as the electric fuel pump and the fuel gauge sender, which work together to deliver an efficient and reliable driving experience.
One of the standout features of the Jeep Grand Cherokee's fuel tank is its inclusion as part of the Evaporative Emission Control System (EVAP). This system plays a crucial role in preventing vapour loss, ensuring that the vehicle's fuel system is sealed and that vapours do not escape into the atmosphere. By minimising vapour loss, the EVAP system contributes to the vehicle's overall fuel efficiency and environmental performance.
The EVAP system works by capturing and storing fuel vapours from the fuel tank in a charcoal canister. These vapours, which would otherwise be released into the atmosphere, are then drawn back into the engine and combusted along with the liquid fuel. This process not only reduces harmful emissions but also helps to maintain optimal engine performance and fuel economy.
Over the years, the Jeep Grand Cherokee's fuel tank has undergone some changes in design and material. Earlier models may have used metal tanks, typically made of steel or aluminium, which are durable but susceptible to corrosion and rusting. More recent models have favoured plastic tanks, made from High-Density Polyethylene (HDPE), which offer improved corrosion resistance, although they may be more brittle under extreme stress.
The fuel tank capacity of the Jeep Grand Cherokee varies slightly depending on the model year. For example, the 2021 model has a fuel tank capacity of 24.6 gallons (approximately 87 litres), while the 2023 and 2024 models offer a slightly smaller 23-gallon tank. Despite these differences, all models boast impressive fuel efficiency, with the 2024 model delivering up to 23 miles per gallon for combined street and highway driving and up to 26 miles per gallon on the highway.
