Find out the Impact of Water Hammer on Cars and Solutions!

Water hammer is a phenomenon that occurs in piping systems when there is a sudden change in fluid flow, causing high pressure and often resulting in system damage. In the context of a vehicle, water hammer can be a serious threat, disrupting the performance of the hydraulic system and threatening driving safety. Let’s explore more about this phenomenon, its causes, impacts, and preventive measures in this  TransTRACK article.

What is Water Hammer in Cars?

Water hammer occurs when a car is in flood conditions and the engine sucks up water from the surrounding environment, including water on the surface of the flooded road.

When the engine sucks up water quickly, the sudden pressure of water into the air intake system or engine cooling system can cause an effect similar to water hammer. This can produce a sound similar to knocking or thumping inside the engine.

Water hammer that occurs in cars during flooding is usually not destructive, but it can be a warning sign that water is getting into the engine system. If water gets into the engine system, it can cause serious damage. Therefore, if you hear strange noises while the car is in flood conditions, it is important to have it checked by a skilled mechanic immediately and take the necessary steps to prevent further damage to the engine.

The Process of Water Hammer in Cars

The process of water hammer in cars is related to water entering the combustion system or lubrication system of the car. This can happen for several reasons, such as leaks in the cooling system, absorption of water from the surrounding environment (for example, when the car is in flood conditions), or condensation of water in the system. Here is a more detailed explanation:

Water Entering the Combustion Chamber and Lubrication System of the Car

Water can enter the combustion chamber or lubrication system of a car through some gaps or leaks in the system. This can happen if there is a leak in the cooling system, which allows water to enter the combustion chamber through a crack in the cylinder head or engine block. In addition, water condensation can also occur within the lubrication system or other systems, especially if the car is used infrequently or if the car operates in cold weather conditions.

Increased Pressure in the Combustion Chamber

When water enters into the combustion chamber, it will burn along with the fuel when the engine is started. This combustion process results in increased pressure within the combustion chamber, as the water will also vaporize and contribute to the volume of gas produced during the combustion cycle.

Increased Piston Thrust

The presence of water in the combustion chamber can lead to increased pressure as the combustion process takes place. This results in a greater push on the piston, which moves downward during the combustion cycle.

Possible Damage to the Piston or Other Components

If too much pressure or thrust is applied to the piston, it can cause bending or damage to the piston or other components in the engine system. This can happen if there is a significant amount of water present in the combustion chamber or if the engine is subjected to abnormal operating conditions.

Water Enters the Engine from Various Gaps

Apart from the combustion chamber, water can also enter the engine system from various gaps or leaks, one of which is through the exhaust component. Leaks in the lubrication system or other systems can also cause water to enter the engine.

This process of water hammer in cars can cause serious damage to engine components and can impair the performance and reliability of the vehicle. Therefore, it is important to keep the cooling system, lubrication system, and other systems in good condition and perform the necessary maintenance to prevent water ingress and water hammer problems.

The Impact of Water Hammer on Cars

The impact of water hammer on cars is the potential for damage to the engine system, especially to the piston and related components, as well as the risk of leaks in the engine that can interfere with vehicle performance and reliability. Here are the other impacts:

Car Won’t Start

Water hammer can cause the car to not start because excessive pressure on the piston can disrupt the combustion system, causing difficulty in starting the engine.

Piston Damage

Piston damage can occur due to sudden and excessive pressure from water hammer, which can cause bending or cracking of the piston and related components in the engine system.

Leaks in the Engine

Water hammer can also cause leaks in the engine as the high pressure can damage seals and weaker components, allowing water or other liquids to enter the engine system and cause damage or corrosion.

Solutions to Prevent Water Hammer

Solutions to prevent water hammer in cars include:

Avoid Flooded Roads

Avoiding flooded roads is a proactive measure to prevent water from entering the engine system, which can cause water hammer and component damage. Water entering the engine can damage the combustion, lubrication, and hydraulic systems, resulting in costly damage and reduced vehicle performance.

Control Car Speed when Going Through Puddles

When driving through puddles, reducing the speed of the car helps to reduce the sudden pressure on the hydraulic system, which can prevent water hammer and damage. Lower speeds also allow time for water to drain slowly, reducing the risk of damage to hydraulic and engine components and maintaining vehicle stability.

Avoid Driving in Heavy Currents

Avoiding riding in heavy currents is essential as strong water flow can cause water to enter the engine quickly, increasing the risk of water hammer and damage to components. By avoiding swift currents, you can reduce sudden stress on the hydraulic system and minimize the risk of damage caused by water entering the engine.

Avoid Starting the Car When Submerged

Avoiding starting your car when it is submerged in water is an important step to avoid damage to the engine system due to water ingress. Starting the engine while submerged in water can cause water to enter the combustion chamber or lubrication system, which can damage critical components and reduce engine life.

Perform Routine Checks

Performing regular checks on engine systems helps detect and prevent water ingress and water hammer problems. Routine checks include the cooling, lubrication and hydraulic systems, which ensure there are no leaks or damage that could cause water to enter the engine. By performing regular routine checks, you can maintain the performance and reliability of your vehicle and prevent water hammer and related damage.
