Types of Engine Dynamometers
Chassis Dynamometers
Chassis dynamometers are used primarily for testing complete vehicles. They measure power output at the wheels, providing insight into how the vehicle performs under real-world conditions. These dynos are equipped with rollers where the vehicle is driven, allowing for accurate simulations of driving conditions. They are versatile and can accommodate a wide range of vehicles including cars, motorcycles, and trucks.
Engine Dynamometers
Engine dynamometers test engines independently from the vehicle. They are essential for tuning and developing new engine setups. These dynos can measure horsepower and torque, providing critical data for performance enhancements. Engine dynos often use hydraulic or eddy current mechanisms to create resistance against the engine, simulating real-world conditions.
Portable Dynamometers
Portable dynamometers offer flexibility, making them ideal for on-site testing. These units are often lightweight and compact, allowing technicians to transport them easily. They typically use water brake systems to measure engine performance and can handle various engine sizes. Brands like Go Power Systems and Power Dyne offer portable options suited for both small and large engines.
Transmission Dynamometers
Transmission dynamometers are specialized for testing gearboxes and drivetrains. They help in calibrating and evaluating the performance of different transmission systems. These dynos provide valuable information about torque and power delivery through the transmission, ensuring optimal performance.
Brake Dynamometers
Brake dynamometers apply a controlled load to an engine, allowing for detailed testing of performance characteristics. They use water brake or eddy current systems to simulate engine loads, making them suitable for comprehensive performance testing. Brands like Froude and Machinio specialize in brake dynamometers.
How to Choose the Right Engine Dyno
Consider Your Needs
When selecting an engine dynamometer, consider the primary application. If you need to test complete vehicles, a chassis dynamometer is the most appropriate choice. For engine-specific testing, an engine dynamometer is essential.
Power Requirements
Different dynos come with various power ratings. Ensure you select a model that can handle the power output of the engines you plan to test. This is crucial for accurate measurements and longevity of the equipment.
Load Mechanism
Understanding the load mechanism is vital. Water brake systems are common for their effectiveness in simulating real engine loads. Eddy current systems offer precise control over resistance and are ideal for tuning applications.
Budget Considerations
Used engine dynos can vary significantly in price. Research various brands and models available on platforms like gopowersystems.com and www.racingjunk.com to find a unit that fits your budget while meeting your requirements.
