The Land Rover Discovery is a versatile and luxurious SUV that offers a range of features and capabilities to suit different needs and preferences. One of the most important aspects of any vehicle is its engine, which determines how it performs on the road and how much fuel it consumes. In this article, we will explore how the Land Rover Discovery Engine 2.0 delivers superior performance and efficiency, and what makes it stand out from other engines in its class.
What is the Land Rover Discovery Engine 2.0?
The Land Rover Discovery 2.0 Engine is a four-cylinder, turbocharged, petrol engine that powers the Land Rover Discovery models. It is part of the Ingenium family of engines, which are designed and manufactured by Jaguar Land Rover in the UK. The Ingenium engines are built to be lightweight, compact, and modular, allowing them to be used in different vehicles with minimal modifications.
The Land Rover Discovery Engine 2.0 has a displacement of 1,997 cc and produces 221 kW (296 hp) of power and 400 Nm (295 lb-ft) of torque. An eight-speed automatic transmission that offers fast and seamless shifting is mated to it. The engine also features a mild hybrid system that uses a belt-integrated starter generator (BISG) to recover energy during braking and coasting, and store it in a battery. The stored energy can then be used to assist the engine during acceleration, reducing fuel consumption and emissions.
How does the Land Rover Discovery Engine 2.0 deliver superior performance?
The Land Rover Discovery Engine 2.0 delivers superior performance by combining high power output, low weight, and advanced technologies. Several essential components that enhance its functionality include:
Variable valve timing:
The engine uses a dual independent variable cam timing (DIVCT) system that adjusts the timing of the intake and exhaust valves according to the driving conditions. This optimizes the airflow into and out of the cylinders, improving combustion efficiency and power delivery.
Twin-scroll turbocharger:
The engine uses a twin-scroll turbocharger that splits the exhaust gases into two streams, one for each pair of cylinders. This reduces interference between the cylinders, increasing the pressure and speed of the exhaust gases, and enhancing the turbocharger response and efficiency.
Direct injection:
The engine uses a high-pressure direct injection system that injects fuel directly into the combustion chamber at precise timings and quantities. This improves the air-fuel mixture formation, resulting in more complete combustion and lower emissions.
Intelligent stop-start:
The engine uses an intelligent stop-start system that automatically shuts off the engine when the vehicle comes to a stop, and restarts it when the driver releases the brake pedal or presses the accelerator pedal. This lowers emissions and fuel consumption while idling.
Mild hybrid system:
The engine uses a mild hybrid system that recovers energy during braking and coasting, and uses it to assist the engine during acceleration. This reduces the engine load and fuel consumption, as well as improving performance and drivability.
How does the Land Rover Discovery Engine 2.0 deliver superior efficiency?
The Land Rover Discovery Engine 2.0 delivers superior efficiency by using less fuel and emitting less carbon dioxide than other engines in its class. According to the official WLTP (Worldwide Harmonised Light Vehicle Test Procedure) figures, the Land Rover Discovery Engine 2.0 has a combined fuel consumption of 9.6 L/100 km (29.4 mpg) and a combined CO2 emission of 217 g/km. These figures are lower than those of some of its competitors, such as the Audi Q7 3.0 TFSI (10.7 L/100 km, 244 g/km), the BMW X5 xDrive40i (10.8 L/100 km, 246 g/km), and the Mercedes-Benz GLE 450 4MATIC (11 L/100 km, 250 g/km).
The Land Rover Discovery Engine 2.0 achieves this level of efficiency by using various technologies that reduce friction, weight, and drag, such as:
Aluminium construction:
The engine is made of aluminium, which reduces its weight by about 20% compared to a conventional cast iron engine block. This lowers the overall vehicle weight and improves fuel economy.
Low-friction pistons:
The engine uses low-friction pistons that have a diamond-like carbon (DLC) coating on their skirts. This reduces friction between the pistons and the cylinder walls, improving efficiency and durability.
Electric water pump:
The engine uses an electric water pump that operates independently of the engine speed. This allows for more precise control of the coolant flow and temperature, improving cooling efficiency and reducing parasitic losses.
Aerodynamic design:
The engine has an aerodynamic design that minimizes air resistance and drag. For example, it has an active grille shutter that closes when the engine does not need cooling, improving the airflow around the vehicle and reducing fuel consumption.
