Frequently Asked Questions

The answers and information you lot need to become the most from your Kawasaki engine.

How does a 4-bicycle (4-stroke) engine work

Are 4-cycle and 4-stroke the aforementioned thing?

Aye, "cycle" and "stroke" are the same. A four-cycle (iv-stroke) engine goes through four steps to generate ability. A two-bike (2-stroke) engine, often used in small mitt-held equipment, goes through 2 steps to generate power.

How does a 4-cycle engine operate?

In a four-cycle engine, the piston takes four cycles (strokes) to complete its move bike.

• Intake Stroke: The intake valve opens as the piston slides to the bottom of the cylinder which brings air and fuel into the cylinder.
• Pinch Stroke: The intake valve closes and the piston slides support the cylinder, compressing the air/fuel mix.
• Power Stroke: The spark plug ignites the mix, pushing the piston dorsum downwardly to the bottom of the cylinder.
• Frazzle Stroke: As the piston moves back up the cylinder the frazzle valve opens and pushes the hot gasses out into the muffler.

What's the difference between air-cooled and liquid-cooled four-bicycle engines?

Air-cooled engines are cooled by the atmosphere. They have fins that help dissipate heat, and often a fan to keep air moving over the hot engine. Liquid-cooled engines accept a liquid-filled radiator and fan to assist cool them.

How to tell a quality lawnmower engine

Are all full general purpose engines made the same way?

No. Kawasaki crankcases are loftier-pressure level die cast, a more than demanding method than typical sand-casting. Crankshafts are forge-quality bandage atomic number 26, not powdered metal. Gaskets are high-temp silicone or metal instead of paper. Pistons are ultra-light blend with a racing-motorbike heritage. Flywheels are heavy cast iron to absorb shock and maintain blade speed. Everyone who assembles an engine besides inpects it, and every finished engine – not but a sample – is examination-run. This results in engines that are consistent, reliable and durable.

Practice the materials that go into an engine really affair?

Loftier quality raw materials are disquisitional. Kawasaki uses automotive-grade aluminum, premium steel, forge-quality iron, and industrial-forcefulness seals and gaskets in every engine to withstand the heat, pressure and loads of heavy extended use.

Is a premium engine worth the extra cost?

The heavy use and loftier loads of commercial lawn mowing is extremely hard on general purpose engines. Some professional landscapers mow more in a week than a homeowner mows in a twelvemonth, and a high-quality engine delivers the reliability and power to keep their lawn mowers running. That ways higher productivity and profit for pros and more years of problem-costless functioning in residential use. Either manner, it'southward well worth the extra toll.

What features or details should I look for in a lawn mower engine?

Selecting a brand known for performance is the best insurance.

Horsepower and torque

What's the difference between horsepower and torque?

Torque is rotating force: the power it takes to turn a wheel or spin a blade. An efficient, productive mower engine requires a precise balance of both - i reason why Kawasaki engineering is so important.

How is horsepower measured?

Typically horsepower is measured on a dynamometer, according to standards defined by the Society of Automotive Engineers (SAE). Engine manufacturers can choose which SAE standard to use. Kawasaki Critical Power engines use SAE J2723, the tightest standard in the industry, with minimum 98% accurateness.

Is a bigger horsepower number amend?

Not always. Depending on the rating formula used, a large number may non testify actual engine power. Look for a Kawasaki Critical Power engine to be certain y'all get precise horsepower.

What does Kawasaki Critical Power mean?

Critical Power is Kawasaki'southward horsepower rating method, based on the industry's tightest rating standard: SAE J2723. A Critical Power rating is at least 98% accurate. More than mutual rating methods tin can deliver a horsepower rating that's just 95% accurate, meaning the engine delivers 5% less power than advertised.

Kawasaki Disquisitional Power engines

What is Disquisitional Power?

Critical Power is Kawasaki'southward horsepower rating method using the tightest standard in the industry, to ensure consistently accurate power. Kawasaki Disquisitional Power engines are certified authentic by SAE.

How practise Critical Power engines compare to other engines?

Disquisitional Ability engines deliver at least 98% of rated horsepower. Conventional engines can deliver as little as 95% of rated power, compromising performance and productivity.

How is a Critical Power engine power-rated?

Disquisitional Power engines are horsepower tested post-obit the SAE J1995 method, verified by the TUV Rheinland Grouping, and and then certified according to a strict SAE J2723 protocol. Most lawnmower engines do non apply this enervating arrangement, and Kawasaki Disquisitional Power engines were the first to have accurate certified power by SAE.

Near fuel: ethanol, E-85, premium and more

What is ethanol gasoline, and should I use information technology?

Regular pump gas is usually a blend of 90% lead-gratis gasoline and x% ethanol (Due east-10). You tin can use this fuel in any Kawasaki lawnmower engine.
