Comment: Under Types of Fuel, the definitions for Dual Fuel and Bi-Fuel appear to be switched. A Bi-fuel vehicle carries both fuels, but only runs on one at a time, and is switched either manually or automatically as needed, where a dual fuel vehicle carries 2 fuels and burns both simultaneously.

Comment: This applies to all parts modules in all years. Students continue to request color diagrams, especially if they are buying online modules. Seems like that should be an easy thing, as the instructor's online modules have color diagrams already.

Comment: On Objective Two Exercise, question #2, it asks what four (4) other components can be driven by a camshaft. The answer is found on page 16, where there are 5 (five) possible answers. Please correct the question to reflect the number of answers listed in the module, and also correct the answer section on page 53.

Comment: Consider rearranging the Catalyst Materials section on the top of page 4 to read "1. oxygen reduction, 2. oxidizing", along with rearranging the subheadings on pages 4-6 to match. In modern converters, since the reduction happens first followed by oxidizing, it makes more sense to teach this way to help with retention. The current formatting in the module leads to confusion as it is taught in reverse order.

Comment: First paragraph statement, "Spring rate refers to the load required to deflect the spring a given distance (usually 1"). Springs that have a high spring rate require a smaller load to produce a 1" deflection than those with a lower spring rate do." The first sentence is correct; the second sentence is referring to "spring rate" in a different context than the first sentence. It refers to spring rate as a qualitative term closer to flexibility. It continues to refer to the spring rate in this qualitative way onto the next page rather than using a different term. Instead, it could say "Spring rate refers to the load required to deflect the spring a given distance (usually 1"). Springs that flex more easily require less load to produce a 1‑inch deflection than stiffer springs." The following sentence is also referring to spring rate as qualitative rather than the technical use of spring rate, and should also be reworded. "The spring rate of a particular suspension is reduced, and the load range increased when:" It could say, "The flexibility of a particular suspension is reduced and the load range increased when:"

Comment: The first paragraph uses spring rate inconsistently and contradicts itself across sentences. It states: "Progressive leaf spring assemblies have a variable spring rate. These types of leaf springs allow for a higher effective spring rate when the vehicle is unloaded, providing a softer ride. When the vehicle is loaded, the effective spring rate is reduced, providing increased capacity and stiffness. Figure 18 shows a typical progressive leaf spring assembly. As the spring assembly is loaded, its effective length is shortened, causing the effective spring rate to be reduced and the load range to increase. A cam-type bracket is used to accomplish this task. As the spring assembly is loaded, the point at which the spring contacts the bracket moves toward the centre of the spring, shortening its effective length." Instead, it could say, "Progressive leaf spring assemblies have a variable spring rate. These types of leaf springs provide a lower effective spring rate when the vehicle is unloaded, resulting in a softer ride. As the vehicle is loaded, the effective spring rate increases, providing greater load‑carrying capacity and stiffness. Figure 18 shows a typical progressive leaf spring assembly. As the spring assembly is loaded, its effective length is shortened, which increases the effective spring rate and load range. A cam‑type bracket is used to accomplish this task. As the spring assembly is loaded, the point at which the spring contacts the bracket moves toward the centre of the spring, shortening its effective length."

Comment: The last paragraph explains the tempering process for tempered glass and refers to it as annealing, which looks to be incorrect. All glass is annealed, and tempered glass starts with glass that is annealed; it is then put through the tempering process. The critical step in tempering glass is quenching (hot glass is rapidly cooled). It also states that tempered glass is 6 times stronger than "ordinary" glass. It should say: "Tempered glass is 4-5 times stronger than annealed glass."

Comment: Laminated glass - ILM states laminated glass is heated in an oil bath at 70 degrees C. This is incorrect; it looks like bonding is performed using heat and pressure, not oil. The temperature is not 70 degrees C, it is 100 - 150 degrees C.

Comment: Legislation that affects the glass industry - MVSS does not directly set standards for adhesives and their ability to bond. FMVSS and CMVSS set vehicle safety performance requirements (such as windshield retention in a crash). Adhesives performance is critical to meeting these standards. Urethane adhesives are not “FMVSS‑approved” products. Manufacturers self‑certify that their adhesives can meet FMVSS requirements when properly installed.
