What are the differences between EA113 and EA888?
2 Answers
The differences between EA113 and EA888 are as follows: 1. Different emergence times: The EA113 engine actually first appeared in 1993, while EA888, as a newer engine series of the Volkswagen Group, appeared in March 2008. 2. Different technologies used: The 2.0TFSI engine of EA888 replaces the traditional timing belt (TIMING-BELT) with a timing chain (TIMING-CHAIN), which is also the first time the Volkswagen Group has used a timing chain on a four-cylinder engine. This design basically means no special maintenance is required throughout its lifespan, with lower noise and no backlash, eliminating the hassle of replacing the timing chain after 60,000-100,000 kilometers of use in the old EA113. At the same time, the EA888 engine uses camshaft phase adjustment technology, with VANE-TYPE as the control device, making the variable timing more accurate. 3. Different volume and weight: The crankcase of the 2.0TFSI engine of EA888 is more than 25% lighter and smaller in volume and weight than the old EA113, and the position of the dual balance shafts is placed in a more reasonable position, which can be directly driven by the crankshaft through a gear set, reducing engine components while slightly improving overall smoothness and stability.
The differences between the EA113 and EA888 are quite significant. Let me explain from a technical perspective. The EA113 is an older generation engine series from Volkswagen, commonly found in 2000s models like the Passat and Golf. It features a cast iron cylinder block with a relatively simple design, known for its durability but also heavier weight, which results in slightly higher fuel consumption and average power output. The EA888, on the other hand, is a newer platform that gained popularity after 2010, often seen in models like the Tiguan and Audi A3. It utilizes a lightweight aluminum cylinder block to reduce overall vehicle weight and incorporates turbocharging and direct injection technologies, improving fuel efficiency and delivering more horsepower. Additionally, the EA888 integrates a variable valve timing system, optimizes emission control to meet Euro 6 standards, and offers much better environmental performance. Overall, the EA113 suits those who prioritize affordability and durability, while the EA888 better meets modern driving demands with faster acceleration and significantly better fuel economy. If you're considering buying a car, most new models now come with the EA888.
