NOx vs Soot Trade-Off in Diesel Engines
What Is the NOx vs Soot Trade-Off? In diesel combustion, reducing one emission often increases the other. NOx (Nitrogen Oxides) form at high combustion temperatures. Soot (particulate matter) forms in…
Combustion Phasing in Diesel Engines
What Is Combustion Phasing? Combustion phasing refers to the exact crankshaft angle at which peak cylinder pressure occurs during combustion. In simple terms: It defines when the maximum pressure happens…
Ignition Delay in Diesel Engines Explained
What Is Ignition Delay in Diesel Engines? Ignition delay is the time interval between: The start of fuel injectionand The actual beginning of combustion. In compression-ignition engines, fuel is injected…
P0110 + P0120 – Intake & Throttle Fault?
When P0110 + P0120 appear together, the issue typically affects air intake temperature measurement and throttle position monitoring. These two sensors directly influence fuel injection calculations and throttle response. Incorrect…
Pilot Injection Explained: Why Modern Diesels Are Quieter
What Is Pilot Injection in Diesel Engines? Pilot injection is a small amount of fuel injected into the combustion chamber before the main injection event. Modern diesel engines no longer…
