Title 40
SECTION 89.405
89.405 Recorded information.
§ 89.405 Recorded information.(a) The information described in this section must be recorded, where applicable, for each test.
(b) Engine description and specification. A copy of the information specified in this paragraph must accompany each engine sent to the Administrator for compliance testing. The manufacturer need not record the information specified in this paragraph for each test if the information, with the exception of paragraphs (b)(3) and (b)(9) of this section, is included in the manufacturer's application for certification.
(1) Engine-system combination.
(2) Engine identification numbers.
(3) Number of hours of operation accumulated on engine.
(4) Rated maximum horsepower and torque.
(5) Maximum horsepower and torque speeds.
(6) Engine displacement.
(7) Governed speed.
(8) Idle rpm.
(9) Fuel consumption at maximum power and torque.
(10) Maximum air flow.
(11) Air inlet restriction.
(12) Exhaust pipe diameter(s).
(13) Maximum exhaust system backpressure.
(c) Test data; general. (1) Engine-system combination.
(2) Engine identification number.
(3) Instrument operator.
(4) Engine operator.
(5) Number of hours of operation accumulated on the engine prior to beginning the warm-up portion of the test.
(6) Fuel identification.
(7) Date of most recent analytical assembly calibration.
(8) All pertinent instrument information such as tuning, gain, serial numbers, detector number, and calibration curve numbers. As long as this information is available for inspection by the Administrator, it may be summarized by system number or analyzer identification numbers.
(d) Test data; pre-test. (1) Date and time of day.
(2) Test number.
(3) Intermediate speed and rated speed as defined in § 89.2 and maximum observed torque for these speeds.
(4) Recorder chart or equivalent. Identify the zero traces for each range used, and span traces for each range used.
(5) Air temperature after and pressure drop across the charge air cooler (if applicable) at maximum observed torque and rated speed.
(e) Test data; modal. (1) Recorder chart or equivalent. Identify for each test mode the emission concentration traces and the associated analyzer range(s). Identify the start and finish of each test.
(2) Observed engine torque.
(3) Observed engine rpm.
(4) Record engine torque and engine rpm continuously during each mode with a chart recorder or equivalent recording device.
(5) Intake air flow (for raw mass flow sampling method only) and depression for each mode.
(6) Engine intake air temperature at the engine intake or turbocharger inlet for each mode.
(7) Mass fuel flow (for raw sampling) for each mode.
(8) Engine intake humidity.
(9) Coolant temperature outlet.
(10) Engine fuel inlet temperature at the pump inlet.
(f) Test data; post-test. (1) Recorder chart or equivalent. Identify the zero traces for each range used and the span traces for each range used. Identify hangup check, if performed.
(2) Total number of hours of operation accumulated on the engine.
