Most call them ‘outboards’, some call them ‘outboard motors’, and a rare few call them ‘outboard engines’, but what are these enigmatic beasts sitting on our transoms?
Diesel engines are notoriously smoky, producing much more blue, white, and black smoke than their gasoline-powered counterparts. The fundamental reasons for this are that diesels operate at higher pressures, with lower-purity fuel, and variable fuel-air ratios. This post covers the different types of smoke, and their (complicated) causes.
The short answer is that it’s our modern take on an old type of tool. The long answer is… longer.
Almost every compression testing guide tells you to hold the engine’s throttle wide open during a compression test, but most won’t tell you why it may (or may not) matter.
Long and short-term fuel trim are very useful indicators of engine performance relative to the manufacturer’s specifications, but before we get into what they tell you, we’ll go over what they are.
There are a few different tests for oxygen sensors (also known as lambda sensors), some of which can be run without dedicated tools. The most effective tests tend to be done under normal operating conditions, on a sensor installed on an engine system, though there are some tests which can be done off-vehicle. You can test oxygen sensors with the following tools: Multimeters Clamp-Meters Oscilloscopes The ST05 Oxygen Sensor Tester Caution: Be sure to follow the oxygen sensor manufacturer’s precautions when testing, as well as the tool manufacturer’s directions, and read the vehicle (or other system) service manual before doing any test. Oxygen sensors get very hot when in use, be careful! But wait! Before testing anything, you need to know what kind of sensor you are working with, and where it is.
Glow plugs are installed on many diesel engines to help with cold starts. They usually fail because of corrosion, overheating, mechanical damage, or metal fatigue, and their failure can cause a variety of problems. The easiest way to test a glow plug is by using a clamp-meter, though digital multimeters can also do the job, and glow-plug testers also work. We will cover the following topics in this post: What is a Glow Plug? What are the Symptoms of a Failing Glow Plug? How to Test Glow Plugs with a Clamp-Meter How to Test Glow Plugs with a Digital Multimeter How to Test Glow Plugs with a Glow Plug Tester Caution: Be careful to follow the glow plug manufacturer’s precautions when testing, as well as the test tool’s directions/manual, and read the vehicle (or other system) manual before doing any test.
The GTC063 is a set of fuse socket connectors, which includes six sizes: ATC/ATO, Mini, Maxi, Low-profile Mini, Micro-2 and Micro-3. These fuse socket connectors are ergonomically designed for easy insertion and extraction, have standard size connection tabs, and are built with corrosion-resistant electrical contacts for maximum conductivity and durability, and molded over with an ABS plastic insulating body. These fuse socket connectors can be used for measuring circuit voltage and current, acquiring waveforms, as well for customizing, extending, and modifying circuits. These versatile connectors are available in a variety of combination packs, and can also be ordered in bulk. For more information call toll free 1-800-440-5582 or visit us at www.gtc.ca
One of the questions we hear most often is ‘what is a wasted spark?’. Wasted sparks are also known by many other names, including ‘waste sparks’, ‘exhaust sparks’, which adds to the confusion.
