Types of Dynamometers
Chassis Dynamometers
Chassis dynamometers are designed to measure the power output of a vehicle at the wheels rather than the engine. This type of dyno is ideal for tuning automotive performance, as it takes into account the entire drivetrain, including losses from the transmission and differential. Dynojet, available at www.dynojet.com, offers several models that can be upgraded over time, making them a versatile choice for performance shops.
Engine Dynamometers
Engine dynamometers focus specifically on measuring the output of an engine, independent of the vehicle’s drivetrain. These are primarily used in engine testing facilities, allowing for precise measurements of horsepower and torque. Companies like Go Power Systems, found at gopowersystems.com, often refurbish used engine dynos, offering a more cost-effective option for businesses.
Inertia Dynamometers
Inertia dynamometers are best suited for small engines, such as those found in motorcycles or go-karts. They measure the acceleration of a spinning mass, providing a reliable indication of engine performance. NR Racing, listed at www.nrracing.com, specializes in inertia dynos and provides custom solutions for various applications.
Eddy Current Dynamometers
Eddy current dynamometers are capable of simulating various load conditions, making them ideal for high-performance engine testing. They are often used in research and development settings. With the ability to measure output under different load conditions, they provide detailed performance data.
Hydraulic Dynamometers
Hydraulic dynos use hydraulic brakes to create resistance against which the engine must perform. This type of dynamometer is commonly used for testing heavy-duty engines, and they can handle larger horsepower outputs. Their robust design makes them suitable for industrial applications.
Used/Refurbished Dynamometers
For those on a budget, purchasing used or refurbished dynamometers can be a smart choice. Companies like Froude, available at www.froudedyno.com, offer used dynos that are refurbished to meet high standards. This option can provide significant savings without sacrificing quality.
Key Considerations When Buying a Dynamometer
Purpose of Use
Before purchasing a dynamometer, it’s essential to identify its intended use. Are you looking to tune automotive performance, test small engines, or evaluate heavy-duty vehicles? Each type of dyno serves different purposes, so knowing your needs is crucial.
Space and Installation
Consider the space available in your shop or facility. Some dynos require more room due to their size or the need for additional equipment. Proper installation is also important to ensure accurate measurements and safe operation.
Budget
Dynamometers can vary significantly in price, depending on their type and features. Establishing a budget will help narrow down your options. Remember that while used dynos can save money, you should also consider potential refurbishment costs.
Upgradeability
Many modern dynos are designed to grow with your business. For instance, Dynojet’s chassis dynamometers can be upgraded over time, allowing you to expand your capabilities without needing to purchase an entirely new machine.
Technical Features
Different dynamometers come with varying technical features. Look for specific measurements you require, such as torque, horsepower, and data logging capabilities. These features will guide you in choosing the right dyno for your application.
Technical Features Comparison
| Dynamometer Type | Data Logging | Accuracy | Load Simulation | Upgrade Options |
|---|---|---|---|---|
| Chassis Dynamometer | Yes | High | Yes | Yes |
