In an effort to decrease emissions from heavy-duty diesel engines faster, CARB's Carl Moyer Program funds upgrades that are in advance of regulations. The California ARB standard for light vehicle emissions is a regulation of equipment first, with verification of emissions second.
On September 21, 2021, CARB proposed a plan to upgrade all engines in cars, trucks, and boats to EPA "Tier 3" levels [34] by the end of 2024, and the "Tier 4" level, which is more restrictive, by 2035. [35] Tier 4 engine technology does not yet exist.
Consumption map of a 1.5-litre three-cylinder diesel engineA consumption map or efficiency map [1] is a chart that displays the brake-specific fuel consumption of an internal combustion engine at a given rotational speed and mean effective pressure, in grams per kilowatt-hour (g/kWh).

The directives cover diesel engines, spark-ignition engines, constant-speed engines, railcars, locomotives and inland waterway vessels. [4] [7] In Europe, the term "non-road mobile machinery" (NRMM) is used to clarify that the definition refers to non-road engines that are capable of self-propulsion. [7]
The Navistar DT (Diesel Turbocharged or Diesel Turbo) engine family is a line of mid-range inline-6 diesel engines.With horsepower ratings ranging from 170 hp (130 kW) to 350 hp (260 kW), the Navistar DT engines are used primarily in medium-duty truck and bus applications such as school buses, although some versions have been developed for heavy-duty regional-haul and severe-service applications.
The Detroit Diesel Series 60 is an inline-six 4 stroke diesel engine produced from 1987 to 2011. At that time, it differed from most on-highway engines by using an overhead camshaft and "drive by wire" electronic control. In 1993, it was popular on many USA buses in the 11.1 L (677 cu in) displacement.
The Caterpillar C175 is a family of diesel internal combustion engines made by Caterpillar. The engine is 5.3 litres per cylinder in displacement. The cylinder size is 175 millimetres (6.9 in) x 220 millimetres (8.7 in) bore/stroke. The engine can produce 1500-4800 horsepower at 1800 RPM. The peak torque occurs at an
