Sheet 1: Data Template

2019.10.23 v002.0
Engine Map Data Sheet
Regulatory references: 40 CFR 1065.510 and 1065.610
	Engine Family
	Date of Map
	Ambient Conditions of Engine Map
	Barometer
	Temperature
	Humidity
	Indicate Step or Continuous Sweep Map (1065(b)(5)(i)
	Record Checkpoint Speed
	If Checkpoint Speed Not Achieved, Provide explanation
YES/NO	Unsafe-- (you should describe why it is unsafe)
YES/NO	Unachievable (rev Limiter or Governor)
	If Engine Governed indicate Speed Setting
YES/NO	Governor?
YES/NO	Rev Limiter?
	Speed Setting of Above
	Describe the method of speed limitation
	Describe how you notify your customers or the installer of a prop or of the engine into a vessel, of the speed range this engine can be operated, and what maximum recommended speed is?
	On The Map Data Sheet, Identify the following values from 1065.610:
	Pmax
	High and Low values of 98% Pmax (interpolate if needed)
	FnPmax
	Maximum Value of S(Pnorm2 + fnorm2)
	High and low 98% points of S(Pnorm2 + fnorm2) (interpolate if necessary)
	fntest, maximum test speed
	If the provisions of 1045.501(f) is used, state the declared Maximum Test Speed (it must be within 500 rpm of the measured maimum test speed)
	Additionally you should supply the following information in spreadsheet format:
	Provide the timebase, speed, load, and power data for the power map on the noted worksheet
	Show your work in tabulating Pnorm (notmalized power) and fnorm (normalized speed).
	Show your work in tabulating S(Pnorm2 + fnorm2)
	Identify all of the above values in the analysis
	If you cannot identify the higher 98% power or higher 98% S(Pnorm2 + fnorm2) value, because the map terminated too soon, you may use the highest speed achieved during the map if it is at least as high as the nominal governor or rev limiter speed. You are attesting with this application that this speed limiting function is installed and functioning for this family's production and at the stated nominal speed, and it is expected that in-use engines would be limited in this way.
	If any alternate procedures were used in mapping the engine, including as provided for in 1065.10 or 1065.510(b)(5)(iv), or any other regulatory provision, you should describe the procedure and contact EPA to request approval.
	Paperwork Reduction Act Notice
	The public reporting and recordkeeping burden for this collection of information is estimated to average 453.79 hours per respondent.
