Issues regarding the use of dynamometers

A dynamometer is basically a tool to deliver an effective comparison or analysis of an engine output or performance. Dynamometers are a lagging indicator, which means the dyno only tells you what has occurred during the dyno run or test period. After you have applied your best engine building skills, the dyno serves the purpose of evaluating the engine’s capabilities at a specified moment in time. A dynamometer mainly measures Horse Power (usually at the crank shaft but in the case of a chassis dyno, Horse Power is only measured at the rear axle), torque, RPM range over which the engine was tested, temperature and air flow (volume and velocity of the air that ventilates the engine). Some dynamometers also …

10 Tips For Getting Your Car Ready For Warm Weather Driving

The first warm weekend of the season traditionally triggers a symphony of cleaning products, vacuums and garden hoses. But while you might be in a hurry to put a shine on your vehicle, it’s equally important to make sure it’s ready for the warm weather on the inside as well as the outside. “The most critical areas to check after the harsh winter months are engine fluids, radiator hoses, belts, tires and brakes,” says Pat Goss, host of PBS’ “MotorWeek” and Washington Post automotive columnist. “Adequately preparing these key areas of the car before the weather warms up will not only keep you safe while driving, they’ll help prevent costly repairs.” After battling months of snow, sleet and icy roads, …

How to Keep Your Tires in Good Shape for a Long Time

Your vehicle’s tires are actually synthetic rubber which has been shaped into its form. It covers the circumference of the wheel of a vehicle. What it actually does is it dampens any strong shocks or forces that could be the effects of any irregularities on the road surface like bumps or potholes. In fact, tires also protect the wheel itself from wearing out too soon. That is why it is of utmost importance that a car owner should take extra care when it comes to the tires. One of the most common ways of keeping a tire in good shape and condition would be to maintain the proper air pressure. Make this activity a routine and do it regularly. And …

How dynamometers work

Dynamometers or dyno systems seem complicated but once you understand the basics it all becomes clear! A dynamometer is basically just a measuring tool, in the same way as voltmeters, scales or speedometers are. Among force-measuring devices, dynamometers are a flexible metallic ring that bends when a force is applied in such a manner as to tend to collapse it (the amount of bending being a measure of the applied force) and a hydraulic “load cell” that measures compressive loads in terms of fluid pressure. Once you have built your new motor, or fitted any tuning parts, it is very important to visit a good automotive Dynamometer or rolling road. If you don’t, then you will never be able to …

How A Swamp Cooler Works

Swamp coolers are a great and inexpensive way to cool off your automotive shop in the summer. A swamp cooler is essentially a large fan with water-moistened pads in front of it. The fan draws warm outside air through the pads and blows the now-cooled air throughout the house. The pads can be made of wood shavings – wood from aspen trees is a traditional choice – or other materials that absorb and hold moisture while resisting mildew. Aspen wood pads, also called excelsior, need to be replaced every season or two, and generally cost $20 to $40 for a set. Small distribution lines supply water to the top of the pads. Water soaks the pads and, thanks to gravity, …

6 Frequently Asked Questions about Motorcycle Tires

Being inquisitive is part of our nature. Too many questions are asked. Moreover, we need real answers to these questions. In the field of motorcycles, especially on motorcycle parts, we are bombarded with questions about tires. Here are the questions and their corresponding answers. 1. What’s the right tire age? Basically, the principle is the newer the tire the better. However, to make a tire last longer the tire’s age is of lesser importance. But be careful not to buy tires which are over six or seven years old. You will be able to know their date of manufacturing by searching for the three or four-digit number stamped in the tire’s sidewall. For instance, 2101 stands for 21st week of …

Tire Safety: Benefits Of Temperature & Pressure Monitoring

Tires play a critical role in the handling, maneuvering and braking of any motor vehicle. No matter what the type…RV, SUV, utility vehicle or commercial truck, tires are the only thing that contacts the road. Obviously, there is much more than just the vehicle resting on those tires…its overall safe operation is as well. By following some basic tire safety practices, you will not only drive with a greater degree of security, you will extend the usable life of your tire investment considerably. Tire Manufacturers Agree It is commonly agreed that a primary cause of early tire breakdown and poor tread life is under-inflation. Low tire pressure not only causes excessive heat build-up in the tire, creating dangerous driving conditions, …
