Does V Represent Five or Four?
3 Answers
V represents five. Below are the specific details of automotive emission standards: 1. China III Emission Standard: Implementation times were July 1, 2009, for light-duty diesel vehicles; July 1, 2010, for heavy-duty gasoline vehicles; and July 1, 2008, for heavy-duty gas vehicles and heavy-duty diesel vehicles. 2. China IV Emission Standard: Nationwide implementation times were July 1, 2013, for light-duty diesel vehicles and heavy-duty gasoline vehicles; January 1, 2011, for heavy-duty gas vehicles; and July 1, 2013, for heavy-duty diesel vehicles. 3. China V Emission Standard: The nationwide implementation of the China V emission standard began on July 1, 2017, which reduces nitrogen oxide emissions by 25% compared to the China IV standard and introduces stricter PM emission limits. 4. China VI Emission Standard: The China VI standard will be divided into two phases, 6A and 6B. The first phase, starting from July 1, 2020, prohibits the sale, registration, and licensing of vehicles below the 6A emission standard. The second phase, starting from July 1, 2023, prohibits the sale, registration, and licensing of vehicles below the 6B emission standard.
Regarding your question about whether V stands for five or four, I think this is a common misconception in the automotive world. V usually refers to the V-shaped arrangement of the engine, with the number representing the cylinder count, but 4-cylinder and 5-cylinder engines are not mainstream V-type layouts. For example, V6 means six cylinders and V8 means eight cylinders, which are more common and offer stronger performance with higher fuel consumption. Although V4 engines do exist (like in older Saab models or motorcycles), they are rare in modern cars, mostly replaced by inline-four engines. As for V5, it basically doesn't exist; 5-cylinder engines are typically arranged in an inline layout, like in some older Volvo models. When repairing cars, I often remind friends not to confuse these—the number directly relates to power output and smoothness. If you want fuel efficiency, go for a 4-cylinder; if you're after horsepower, aim for a 6- or 8-cylinder. I recommend checking the specifications when car shopping to confirm details, rather than blindly trusting verbal claims.
Hi, I've driven several cars before and often heard people talk about the numbers in V engines. The V represents the cylinders arranged in a V shape, but the talk about four or five is somewhat non-standard. In reality, 4-cylinder cars like the Toyota Corolla mostly use an inline design (called L4), while V-type engines like the Ford Mustang's V6 are more common; V5 engines are almost non-existent in the market, mostly just rumors. From a daily driving perspective, the number differences affect acceleration and noise: 4-cylinder engines are economical but bumpier, while 5-cylinder engines offer better balance. I once struggled with this knowledge when switching cars, but later I looked it up online and learned that engine codes are combinations of letters and numbers like '2JZ-GTE,' etc. To avoid confusion, don't guess the parameters blindly; the most practical thing is to test drive and experience it yourself. After all, the joy of driving lies in the feeling, so don't let the numbers confuse you.
