4 Stroke Gasoline Engine Model Metal Internal Combustion Engine Physics Experiment Teaching Instrument

Features:


.100% brand new with high quality
.The design is novel and the shape is unique

.The model is made with fine quality and reliable quality, which can visually observe the operation process of the gasoline engine

.Usage: Turn on the power and slowly turn the handle in the direction indicated by the arrow


.Suction stroke: The intake valve is opened, the exhaust valve is closed, and the piston moves downward from the top dead center to the bottom dead center.A mixture of fuel and air enters the cylinder from the intake manifold


.Compression stroke: The intake valve and the exhaust valve are closed, the piston moves from bottom to top,and the fuel mixture is compressed in the cylinder, and the temperature rises rapidly


.Power stroke: When the piston reaches the top dead center, the spark plug is ignited (represented by the bulb at the spark plug)


.The fuel mixture is spotted (the bulb is extinguished to indicate that the ignition is complete). The gas in the cylinder expands rapidly due to being ignited, pushing the piston to start moving downward to the bottom dead center. At this time, the crankshaft outputs power

.Exhaust stroke: Due to the inertia of the rotating mechanism, the crankshaft passes the bottom dead center and the piston moves upward


.At the same time, the exhaust valve is opened and the exhaust gas is discharged from the exhaust pipe.After the exhaust stroke is completed, the exhaust valve is closed, the intake valve is opened, the piston moves downward, a new suction stroke is started, and the next cycle is entered

Very readable treatment of a difficult topic
I thought the book was very easy to read and written as if Mike was in a room with you chatting about this important topic. I think the book is a great resource for anyone dealing with either personal challenges or interpersonal issues with friends, coworkers or family members. A very informative book that deals with a difficult topic in an easy to read writing style.

Good read
"I know you were once an child with dreams but I once your child with my own dreams." Is a quote that relates to this book.While it needs to be edited more and some mistakes fixed, this has allowed me and many others to understand our parents better and work towards fixing what they have done or even what they failed to do.

Guidelines for Self-awareness and change
This book’s focus, to me, was about self-awareness: 1 to what degree were my parents emotionally immature and what impact, if any, did this impact me?; 2. To what degree have I grown and developed in emotional intelligence/nurturing resilience?; and what impact did my behaviors have on my children’s development? An interesting exercise

A Practical Guide to Breaking the Cycle of Emotional Immaturity
“The Legacy of Emotionally Immature Parents: Gain Insights and Solutions Across the Generations to Navigate Child-Rearing Challenges, Build Healthy Relationships, and Grow Emotionally” by Mike Palm is the practical guide for parents who couldn’t fully meet emotional needs, and couldn’t give what they didn’t have and the adults still carrying the impact. The book is quite well structured. For example, Chapters 1–2 define emotional immaturity, trace its roots and explore how it shows up in family dynamics. Chapter 3 focuses on breaking the cycle - identifying patterns, using boundaries, mindfulness, and behavioral change tools. Chapter 5 is on self-care - prioritizing it without guilt, designing routines, balancing family obligations, and practicing emotional detachment. Chapter 7 tackles forgiveness and building a legacy of emotional maturity. Overall, this is a practical guide for anyone who grew up feeling emotionally unseen and wants to parent differently. Highly recommended for parents who recognize emotional immaturity in their upbringing and want to stop the cycle, or anyone wanting to build healthier relationships with family members who may still carry those patterns.
