How is the Volkswagen EA211 engine?
1 Answers
The following are the advantages and disadvantages of the EA211 engine: 1. Lightweight: The EA211 series engine is constructed entirely of aluminum, from the valve cover at the top of the engine to the oil pan at the bottom, all made of aluminum alloy. This makes it significantly lighter than the previous EA111 series. The benefits of lightweighting for front-wheel-drive vehicles (all models equipped with this series of engines are front-wheel-drive) include reducing some undesirable characteristics of front-wheel drive, such as understeer during cornering, nose-diving during braking, and faster wear on the front tires. 2. Fuel-efficient: In addition to weight savings, the EA211 series engine also incorporates fuel-saving technologies. The cylinder deactivation system in the EA211 series automatically shuts off the second and third cylinders when the engine is operating under medium to low loads, thereby reducing fuel consumption. Compared to models without this technology, fuel consumption per 100 kilometers is reduced by approximately 0.4L. 3. Improved efficiency: As one of the core technologies of Volkswagen's MQB modular platform, the EA211 engine features dual variable valve timing for both intake and exhaust, and the direct injection system uses a 5-hole injector with an increased injection pressure of 200bar. These technologies collectively enhance the engine's operational efficiency to some extent. 4. Insufficient power: Among the EA211 series engines, the 1.4T variants with two power outputs are one of the main models. While delivering fuel economy, the EA211 also sacrifices some power. For example, the 1.4T engine in the Bora has a maximum power of only 96 kW and a maximum torque of 225 Nm. The 1.4L models may exhibit insufficient power when climbing hills fully loaded. However, after tuning, the high-power version of the EA211 engine can reach up to 110 kW.
