What is the compression ratio of the Tharu engine?
4 Answers
The compression ratio of the Tharu engine is 9:1, which is a turbocharged engine. The Tharu offers two powertrain models, equipped with 1.4T and 2.0T turbocharged engines respectively. The 1.4T engine delivers a maximum power of 110 kW and a maximum torque of 250 Nm, while the 2.0T engine provides a maximum power of 137 kW and a maximum torque of 320 Nm. Here are some details about the Tharu: 1. Dimensions: The Tharu is a vehicle launched by SAIC Volkswagen, with a length, width, and height of 4453mm, 1841mm, and 1632mm respectively, and a wheelbase of 2680mm. 2. Exterior: The Tharu adopts the Rock Cutting design concept. The raised lines on the backbone-style hood enhance the sense of power, while the wide-body dual U-shaped full LED headlights tilt upwards, with the grille strips extending to the headlights.
I often study car specifications, and the engine compression ratio of SUVs like the Tharu is quite interesting. Its commonly used 1.5TSI engine has a compression ratio of around 10.5:1, which is a well-balanced design that provides good power response while also being fuel-efficient. A higher compression ratio improves combustion efficiency, but if it's too high, it can cause knocking and require higher-octane gasoline; if it's too low, the power output will be weak. The Tharu's setup ensures quick acceleration in city driving and stable fuel consumption of 7-8L/100km on highways. After driving it for several years, I find it quite reliable. Additionally, the compression ratio also affects engine longevity, so regular maintenance, including checking spark plugs and the intake system, is essential. There might be slight variations in different model years, but 10.5:1 is the standard value, making maintenance simple without compromising performance.
After so many years in the repair business, I can say compression ratio is one of the core parameters of an engine. The 1.5T engine in the Tharu has a compression ratio of 10.5:1, which means the cylinder volume after compression is reduced to one-tenth of its original size plus half that amount. This value directly affects combustion efficiency and power output – too high and it risks overheating and cylinder damage; too low increases fuel consumption and carbon buildup. During vehicle inspections, I use a pressure gauge to check compression and identify issues. Abnormal readings may indicate worn piston rings or valve leakage. When customers experience power loss or increased fuel consumption, checking compression-related components is a good first step. Maintenance isn't complicated – just regular oil changes and throttle body cleaning to keep the compression ratio around 10.5 ensures smooth operation and extends vehicle life. The Tharu's well-designed system results in low failure rates, making this particularly practical.
I've been driving the Tharu for two years, and the engine compression ratio is approximately 10.5:1. This number affects daily driving aspects such as refueling frequency and acceleration feel. A higher compression ratio means better fuel efficiency, and in practical use, the urban fuel consumption is about 8L/100km, even lower on highways, with smooth acceleration. During maintenance, the technician mentioned that 10.5:1 strikes a balance between power and economy, making it simple to maintain—just regular servicing without needing special adjustments. Unstable compression ratios can cause shaking, but the Tharu's engine remains stable with no issues, making driving enjoyable. Long-term use confirms its reasonable design; though the compression ratio is an invisible parameter, it genuinely enhances the driving experience and is trustworthy.
