OHV: Understanding the Importance of Overhead Valves in Pressure Washing Equipment

As a home or business owner seeking pressure washing and exterior cleaning services, you might have come across the term “OHV” while researching different pressure washing machines and equipment. In this article, we will delve into the world of OHV (Overhead Valves) and explore its significance in the pressure washing industry. Let’s get started with some basic questions:

What is OHV?

OHV stands for Overhead Valves, which refers to the internal combustion engine design used in some pressure washing machines. This technology involves placing the valves on top of the engine’s cylinder head, as opposed to being placed on the side, like in older engine designs. The OHV system is known for its efficiency and improved performance in pressure washing applications.

Why is OHV important?

OHV engines have gained popularity in pressure washing equipment for several reasons:

Enhanced Efficiency

OHV engines are more efficient compared to older side-valve engines. They provide better fuel economy and reduced emissions, making them more environmentally friendly.

Increased Power

OHV engines deliver more power and torque, allowing pressure washers to handle tough cleaning tasks effectively.

Improved Cooling

The overhead valve configuration allows for better cooling of the engine, leading to longer engine life and improved durability.

Quieter Operation

OHV engines tend to operate more quietly than traditional engines, reducing noise pollution during pressure washing tasks.

How does OHV work?

Understanding the mechanics of OHV can be helpful in appreciating its advantages. Here’s a simplified explanation of how OHV works:

1. Valve Placement: In an OHV engine, the intake and exhaust valves are positioned above the cylinder head. This arrangement enables more direct airflow and efficient combustion.
2. Pushrods and Rocker Arms: OHV engines use pushrods and rocker arms to actuate the valves. When the camshaft rotates, it pushes the pushrods, which then move the rocker arms, causing the valves to open and close.
3. Efficient Combustion: The OHV design allows for a more controlled airflow into and out of the engine’s combustion chamber, leading to better fuel combustion and higher power output.

What are the benefits of OHV?

Choosing pressure washing equipment equipped with OHV engines can offer numerous benefits:

• Increased Power Output: OHV engines generate more power, making them suitable for heavy-duty pressure washing tasks.
• Fuel Efficiency: OHV engines are more fuel-efficient, helping to reduce operating costs for long cleaning sessions.
• Durability: The improved cooling and reduced friction in OHV engines contribute to their longevity and overall durability.
• Lower Emissions: OHV engines produce fewer emissions, promoting a cleaner environment.

Are there any downsides to OHV?

While OHV engines are highly advantageous, it’s essential to consider potential downsides:

Cost

OHV engines may be slightly more expensive initially, but the long-term benefits often outweigh the upfront investment.

Maintenance Complexity

The design complexity of OHV engines can make maintenance and repairs slightly more involved, requiring professional servicing.

What are the alternatives to OHV?

In the pressure washing industry, OHV engines are a popular choice, but there are alternative engine types available:

1. Side-Valve Engines: These are traditional engine designs with valves placed on the side of the cylinder. While they are simpler in construction, they lack the efficiency and power of OHV engines.
2. OHC (Overhead Cam) Engines: OHC engines have the camshaft placed above the cylinder head, directly actuating the valves. They offer some efficiency benefits, but OHV engines are generally preferred for pressure washing equipment.

The History of OHV in Pressure Washing Equipment

The concept of overhead valves (OHV) in internal combustion engines, including those used in pressure washing equipment, has a fascinating history. Understanding this history can shed light on the significance of OHV as a crucial topic for pressure washing companies and enthusiasts.

1. Early Engine Designs: In the late 19th and early 20th centuries, engine designs predominantly used side-valve configurations. These engines were simple and reliable but lacked the efficiency and power of OHV engines.
2. Emergence of OHV Technology: The development of OHV technology can be attributed to the need for increased engine performance and fuel efficiency. In the 1930s, automotive engineers began experimenting with overhead valve designs, leading to significant advancements.
3. OHV in Pressure Washing Equipment: As the benefits of OHV engines became evident in automobiles and other machinery, pressure washing equipment manufacturers recognized the advantages of using OHV engines in their products. OHV-equipped pressure washers quickly gained popularity due to their superior performance and durability.
4. Evolution of OHV Engines: Over the years, OHV engine designs have continued to evolve, incorporating advanced technologies such as electronic fuel injection and variable valve timing. These improvements have further enhanced the efficiency and environmental-friendliness of OHV engines in pressure washers.
