Let\u2019s explore more differences between the overhead valve vs overhead cam engines’ reliability, pros and cons and working.<\/p>\n\n\n\n
Design and Configuration<\/h3>\n\n\n\n![\"OHV](\"https:\/\/d2hucwwplm5rxi.cloudfront.net\/wp-content\/uploads\/2023\/06\/19103011\/OHV-vs-OHC-engine-_-Body-3-19-6-23-1024x640.jpg\")
OHC engines have two types, whereas OHV is a type of pushrod engine<\/figcaption><\/figure>\n\n\n\nAn OHC engine has a camshaft<\/a> on top of the valves, whereas OHV has a camshaft between the valves. That said, both configurations have distinguished functions and working. <\/p>\n\n\n\nOverhead cam engines come in two configurations, i.e. inline or V-engines<\/a>. Meanwhile, the OHV is a type of pushrod engine. Moreover, OHC has two types: dual overhead cam and single overhead cam engines. You can learn the differences between SOHC and DOHC engines<\/a> to understand their design in detail.<\/p>\n\n\n\nAfter the design, another difference between the overhead valve and overhead cam engines is their working.<\/p>\n\n\n\n
Working<\/h3>\n\n\n\n
The overhead cam engines have a camshaft located at the top actuating the valves. The crankshaft<\/a> rotates the camshaft. After that, the lobes push the valve stems, causing them to open and close as the lobes rotate. The valve springs provide the return force, while the timing belt couples the overhead camshafts to the main shaft. <\/p>\n\n\n\nOn the other hand, overhead valve engines have only one cam placed between the V of the cylinder banks on the opposite. The single camshaft lobes actuate the pushrods. These pushrods transmit linear displacement to rockers. Then, the rockers redirect the motion down, pushing the valves downward. <\/p>\n\n\n\n

OHC engines provide higher RPM than the OHVs<\/figcaption><\/figure>\n\n\n\nLearning the advantages and disadvantages of overhead cam engines<\/a> is essential when buying a car with SOHC or DOHC engines.<\/p>\n\n\n\nHere are the benefits of OHC engines:<\/p>\n\n\n\n
- They provide improved performance compared to other engine designs. The direct actuation of the valves allows precise valve timing and greater control over the intake and exhaust cycles, which can result in better overall engine performance.<\/li>
- OHC engines have higher RPM compared to the OHV engine. The lighter valve train and reduced reciprocating mass allow the engine to rev higher, potentially leading to increased power output.<\/li>
- Better fuel efficiency is another advantage of an overhead cam engine compared to the overhead valve. Efficient valve control and reduced internal friction contribute to improved combustion efficiency and reduced fuel consumption.<\/li>
- Variable valve timing <\/a>(VVT) technology is also found in overhead cam engines. <\/li><\/ul>\n\n\n\n
Here are the cons of OHC engines:<\/p>\n\n\n\n
- OHC engines have a complex design with more components compared to the pushrod engines. This complexity increases its weight. Moreover, the manufacturing, maintenance and repair costs are higher.<\/li>
- These OHC engines have a narrow torque band that produces less low-end torque, requiring higher RPMs to achieve maximum power. It can result in a less responsive engine at lower speeds.<\/li><\/ul>\n\n\n\n
Pros and Cons of OHV Engines<\/h3>\n\n\n\n![\"OHV](\"https:\/\/d2hucwwplm5rxi.cloudfront.net\/wp-content\/uploads\/2023\/06\/19104016\/OHV-vs-OHC-engine-_-Body-4-19-6-23-1024x640.jpg\")
Overhead valve engines have better durability and reliability<\/figcaption><\/figure>\n\n\n\nThe following are the advantages of the overhead valve engines:<\/p>\n\n\n\n
- It was part of the classic muscle cars by American auto manufacturers that produced high power and performance.<\/li>
- The OHV engines have a compact size and less weight than the OHC engines due to the less number of camshafts.<\/li>
- Its compact size and design lower manufacturing and maintenance costs.<\/li>
- OHV engines are known for their durability and robustness. Its components reduce the vulnerability to extreme temperatures and potential damage. <\/li>
- OHV engines often exhibit strong low-end torque. It is one of the main differences between the overhead valve and overhead cam engines that require ample pulling power or towing capabilities.<\/li><\/ul>\n\n\n\n
Alongside its advantages, here are the disadvantages of OHV:<\/p>\n\n\n\n
- The OHV design may not provide optimal combustion efficiency compared to other engine configurations. The placement of the valves in the engine block can result in less efficient airflow and fuel mixture compared to engines with overhead cams. <\/li>
- The pushrod design limits the speed at which the engine valves function<\/a>, which can impact the engine’s ability to achieve high RPMs. <\/li><\/ul>\n\n\n\n

When choosing between the OHV vs OHC engines, consider their design, power and performance differences<\/figcaption><\/figure>\n\n\n\nBoth engines have their benefits and drawbacks. It\u2019s important to figure out the power and performance you need while driving a car. <\/p>\n\n\n\n

However, OHC engines can be found in fuel-efficient vehicles, such as the Mercedes C300 and BMW X5<\/a>.<\/p>\n\n\n\nThis was a detailed comparison between the overhead valve vs overhead cam engines.
