Make Sense of Diesel Engine Specs - Frontier Power Products
Torque is “the rotary force in a mechanism” according to a dictionary definition. The two are related (Torque lb-ft = H.P. X 5252 / RPM) but torque is often misunderstood. Since there is a fixed relationship between HP (or kWm) and torque, two engines having the same horsepower at the same RPM will have the same torque.
Tier 4 Frequently Asked Questions | Cummins Inc.
Tier 4 refers to a set of emissions requirements established by the EPA to reduce emissions of particulate matter (PM), oxides of nitrogen (NOx) and air toxics from new, non-road diesel engines.

A new definition of a compression-ignition (diesel) engine was introduced in the 1998 rule, consistent with definitions established for highway engines. The definition focuses on the engine cycle, rather than the ignition mechanism, with the presence of a throttle as an indicator to distinguish between diesel-cycle and otto-cycle operation.

Wet stacking - Wikipedia
Wet stacking. Wet stacking is a condition in diesel engines in which unburned fuel passes on into the exhaust system. [1] The word "stacking" comes from the term "stack" for exhaust pipe or chimney stack. The oily exhaust pipe is therefore a "wet stack". This condition can have several causes.
