Diesel engines are powerful, efficient, and widely used in vehicles, generators, ships, and heavy machinery. However, many people wonder: do diesel engines have spark plugs? The short answer is no—but let’s explore why. Why Diesel Engines Don’t Use Spark Plugs Unlike gasoline engines, which rely on spark plugs to ignite a mixture of air and fuel, diesel...

When a diesel engine turns over (cranks) but fails to start, it can be both frustrating and puzzling. Unlike gasoline engines, diesel engines rely on high compression and precise fuel delivery for ignition, meaning a number of factors can prevent the engine from firing up. Understanding the common causes can help pinpoint the issue quickly and avoid unnecessary downtime. 1. Lack of...

Air starters are widely used for diesel engines in industrial, marine, and oilfield applications where reliability and safety are crucial. These devices use compressed air to rotate the engine’s flywheel, delivering the torque needed to start large diesel engines efficiently, especially in environments where electric starting systems might not be feasible due to explosive atmospheres...

Heavy-duty jump starters have become essential tools for diesel engine owners, especially for those operating trucks, tractors, construction equipment, or marine engines. Unlike gasoline engines, diesel engines demand more cranking power due to higher compression ratios, which is why a standard jump starter often isn’t enough. In this article, we’ll explore the advantages...

The 6.7L Cummins engine is widely known for its power, reliability, and longevity. Found in many Ram heavy-duty trucks since 2007, this diesel workhorse has proven itself in countless demanding environments. However, like all engines, it's not without its issues. Whether you're a fleet manager, diesel mechanic, or DIY truck enthusiast, understanding the most common problems with the 6.7L...

When a diesel engine cranks but won’t start, it usually means the starter is doing its job, but something else is preventing combustion. Here's how to troubleshoot the issue step by step: 1. Check the Fuel Supply Is there fuel in the tank? It sounds simple, but it’s worth checking. Clogged fuel filter or air in the lines can block fuel from reaching the injectors. Make sure...

Manually starting a diesel generator is a practical solution when batteries fail or power is unavailable. Whether your generator uses a hand crank, pull-start mechanism, or a spring starter like the Cqstart, follow this step-by-step guide for a safe and effective startup. ✅ Step 1: Open the Fuel Valve Ensure the fuel valve is fully open to allow proper fuel flow....

When it comes to non-electric engine starting systems, two prominent technologies often come into play: spring starters and hydraulic motors. Both are reliable in extreme environments where electric starters may fail, but they serve different use cases and come with distinct advantages. Choosing between a spring starter and a hydraulic motor depends largely on the application, engine type,...

Diesel engines are known for their durability and fuel efficiency, but like all machines, they’re not immune to problems. Understanding common diesel engine problems can help you maintain your engine better and avoid costly repairs. Hard Starting or Failure to StartThis issue is often caused by faulty glow plugs, low compression, or fuel delivery problems. Cold weather can...

Diesel engines are known for their durability and efficiency, but like any mechanical system, they are not immune to problems. Understanding the most common diesel engine issues can help operators diagnose and fix problems early, preventing costly breakdowns and downtime. 1. Hard Starting or Failure to StartOne of the most common issues is difficulty starting the engine. This can be...
